The serial number on the instrument is 0127.
The ends are made of plastic! (shock, horror etc.) but it still sounds pretty good.
It's more strident that my old Lachenal and has a very tight and "positive" feel to it.
I borrowed a Crabb for a while some years ago and it "feels" like that instrument did, but I also played a relatively new Wheatstone recently and it also reminded me of that instrument.
I've only ever owned older concertinas and playing the new ones is a bit of a shock!
