    Does this case need work

    Given it is a ‘signed’ case, why not ask the case makers..? The Dippers will probably know if they are still around. Lovely case...

    24 key C/G Anglo Lachenal/ Wallis date ?

    I have one of these; the extra buttons on each side are the notes you would expect to find on the first two accidental row buttons.
  3. If the pan is warped then the underside of the action box is likely to be concave as well.
  4. No need to replace the gasket around the outside of the bellows if it is OK. Same for the gasket on top of the partitions but if it needs to be done, you would normally cut it from one piece of chamois but not all in one piece. Make a series of long strips around 3mm wide and apply them piece by piece. Chamois skins can have a lot of variation in thickness, try to make the strips as consistent in thickness as possible.
  5. It would be best to use a leather rather than a modern material for the gaskets. Chamois was common. It is common for the pan blocks to be out of position and the best thing would be to remove them and put them back in the right place. A work flow which would work, barring the unforeseen or so far unmentioned, would be, remove the reedpan blocks, clean them up and also the place they will be reattached, fix the gasket if necessary, place the reed pan in the bellows and place the bellows face down on a flat surface, then from the other end of the bellows put your hand in and push the pan down against the flat surface and refit the pan blocks. This is a little more fiddley than I have made it sound but it is not rocket science. Use a reversible glue, ie. fish or hide, and mistakes become tedious rather than tragic.
  6. The clearance issues are the same with concertina reeds. I have seen on a highest quality Wheatstone concertina the frame tapering in towards the reed in the last few mms to the point there seemed to be no clearance and when this was shown to me it was understood to have been done for precisely the reason the polish is applied in the video. Any gap around the reed is essentially a necessary leak. It is not a surprise only best quality reeds might have had this; apart from the technical difficulties, lesser quality reeds could be more easily improved by lifting the quality of the clearance all round. Once this was done I can imagine someone saying, what else can we do? Do we need this clearance where the reed doesn't really move? I do wonder at clearances figures like 5 to 10 microns at the most? BeePee, how is this being measured? On a harmonica red plate there are not be the forces which shift clearances according to the weather but even so. In a concertina reed you would be asking a reed to not deviate sideways over as much as 20-30mm. Perhaps a surface ground reed might pass this test but a hand filed one?

    “Winterizing” the concertina

    Numbers 1 & 2 on your list are valve issues and yes it is likely the valves are reacting to humidity. (Was this a 40 button from Hazelbrook in the Blue Mountains? If so then I know the instrument, a decent example of its sort and in good condition.) These may settle down but supplying a (consistent) more humid environment would help. Number 3 may also be valves but also could be fluff caught in the reeds, a loose reed shoe, or even a just touching tongue. These often respond to removing the assembly, inspecting for fluff and replacing back in the slot. Many instruments have valve related buzzes and gurgles and top instruments owned by top players often have them too. People learn to play around them. Avoiding changing bellows direction with the button depressed will often eliminate your number 2, which is common on lower notes. The way you express number 1 indicates you can find ways to play around those noises also though it will dictate your phrasing at times. If it does not settle you might need to change the offending valves.

    Fingers slipping

    I used to suffer from fingers slipping but found attention to technique helps. The most common button I had issues with was the f# on the Grow. When I looked at the problem of that button specifically I found I was hitting the button with the flat of the finger and with a lot of sideways movement; the best description of this might be throwing the finger in that vague direction and hoping part of it might hit the spot. This was as a way of coping with the lack of dexterity and strength in the little finger. When I decided to use the end of the finger and be more precise in an up and down movement the issue receded and I rarely slip now, though if it is hot and sweaty I might still have the problem occasionally.
  9. My first thought is the reed frame is loose in the pan. It will not be hard to fix, it has to be one of, the frame is loose, there is something jammed in the reed, or the valve is stuck.

    Wheatstone

    In regard to Anglos they started to use cheaper production techniques, things like non-riveted action, plywood parts, and aluminium reed frames plus the reeds were not always made as well. These were logical ways to stay in business. So it is not hype, but nor can you say everything after a certain date is bad.

    Highs and Lows of concertina playing

    It is a myth, 20 seconds of googling will turn up good scientific sources declaring altitude makes no difference to pitch.
  12. There is no intrinsic reason a note should sound different in an EC/Anglo/Duet. A passage of notes could also be played to sound the same. In practise one can often pick the difference between a Duet/EC player and an Anglo player but I doubt you could easily pick between the EC and Duet players, and never by tone. The better the players the harder it would get. Instruments can be produced to enhance particular tone colourings and a run of one style of instrument by a particular maker could all be similar but it will not be a colouring a maker of different instruments could not emulate given a reasonable level of skill. Tone is best evaluated in person.

    Reed making a rattling sound.

    Temporarily tape the valve next to the reed shut with a tiny scrap of the weakest tape you can find. If the noise disappears replace the valve.

    making a 40 button anglo

    Hey, go for it. One word of caution, in regard to using parts from a traditional concertina to make one with accordion reeds. I can't think of a single accordion reeded anglo concertina with more than 30 keys. (Happy to be corrected, anyone?) My understanding is the reeds take up more room than traditional concertina reeds and it is not possible to fit them into the same size carcass. This would mean not being able to use parts from your Lachenal and having to make a larger concertina.
  15. The numbers seem large, could the instrument be in a different pitch? Also, the state and nature of the valves will affect the offset size. Any offset that large and I would change the valve first.
