Hi, sounds like a great concertina.
I got hold of (what I am pretty sure is) a 35 button Lachenal Crane Duet.
I was thinking I might of had to have it tuned, but the notes in C seem to be OK (just getting a feel for the others).
Have to say its a good bit of crac learning it (gave up on the piano when my young fellow passed me out).
Just wondering do you know the best way to go about having a concertina looked over.
I love the look of your 51 button Crane, but I guess its a little soon for me to aspire to one like this!
