This should help clear up the name pronunciation and is a delightful watch as well. David.

I have 9008 Geoff kindly told me it was made by H T Crabb in 1927. David.

It opened ok for me @9.25 am,thank you.

I just measured the card in a 12 sided Lachenal bellows from around 1910 and they are 1".David.

I did a bit of reed cleaning and resetting today.I resisted the temptation to bring them back up a few cents to be bang on, as it would be very difficult to replace them if anything went wrong. I also made a new o ring to go under the lid so alls well and harmonious in the tea department.

Almost looks as if some of the valves (in the chambers) are mount on the other end to usual?

Yes solid nickel silver.The only Wheatstone button I had handy was an early one with an ivory core which I guess would be a little heavier than the beech? or plastic cores.David.

Here is a rough comparison of the weights of a Wheatstone button and some made to the approximate dimensions in nickel and titanium.David.

Spent a very pleasant afternoon being entertained by this group on the last gig of their UK tour.It would be easy to get put off by their name or even their album cover but don't be if you get a chance to see them.They were warm ,generous and skilled musicians.Off course the unique setting/set up of the Square and Compass at Worth Matravers is something I would recommend to anybody visiting this part of the world.Regards David. http://www.squareandcompasspub.co.uk/index.php/component/jevents/eventdetail/876/-/d-bize.html?Itemid=5

Here are some I made myself. Maybe not the correct or best way but they are holding up fine thus far. I used 100g/sm good quality printing paper and then laser printed the design on.I gave them a coat of lacquer and fixed them on to the bellows with flour paste.It is important that they are either printed traditionally or laser printed.regards David.

"this photo of the best dressed box player showing that a concertina will attract the attention of elegant ladies! (Nurse on hand too.)​" Nice playing and nice picture even holding the concertina the right way up in the photo! David.
