Rather than adapt an instrument to suit the case (and risk damaging a vintage instrument), look at making (or acquiring) a slightly larger case.

Any alteration to the depth of the blind drilled holes for the captive nuts (sometimes called receiver plates) may well cause a load of trouble to some restorer in the future. Pulling out the captive nuts can damage the instrument by pulling veneer away with the nut. You may even affect the potential resale value, since putting right any alterations is an expensive process. As a repairer, I would caution against any alteration to a vintage instrument. Looking at the photo, have you tried turning the instrument through 45 degrees in its case? The wrist strap thumbscrews shouldn't then touch the inside of the case.

Look forward to hearing about it and to seeing the pics

Do any of the repairers and restorers here have any vintage wrist strap thumb screws from a scrapper available? I have a requirement for 2x wrist strap screws (Wheatstone Aeola EC), and the corresponding brass receiver plates. Thanks in advance.

As a restorer, given an appreciation for the nature and amount of work involved in a concertina, my guess would be about 1 instrument per month (maximum 2) for a sole maker (maker and assistant possibly 3-5 every 2 months).

At a ceilidh I once witnessed a potentially serious accident between a high-heeled shoe and a sporran.

There is no caller usually at Scottish ceilidhs, so that relieves the band of asking which tunes will fit. Dancers are expected to know the dances, and by and large, they do, or can pick them up in real-time.

I recall when I played in a ceilidh band in Edinburgh - we'd play may be 10 dances per hour, and 3 tunes per dance - with a few spares, we played around 100 tunes in a 3 hour set. I can't play any of them now - I went over entirely to Nordic folk music.

FWIW bandos used for Argentinian tango (Rheinische tonlage) I read that they are tuned to A=442Hz.

Still available Here's a video.

Here's a video of this instrument in action.

Here are some pictures of the rebuild process.
