No splits or cracks! The bridging is solid and the neck is straight. There is hope!
I just found a picture of the tailpiece on a Menzenhauer & Schmidt Mandriola! Probably worth more than the mandolin, hey?
I think Vintage Fretshop has limited hours these days. I bought something from David last year and he was mostly around i think Thursday and Friday, maybe that is it. I would still try to catch him in terms of getting screw for the gear. You could try some std ones, I suppose. I would take one of the others out to compare to a new one. Good luck.
Glid those tailpieces are available from Stewart Macdonald here.
Bill, thanks for the link!
Jim, Dave has done great work on my 1923 Thompson Banjo. He has quite a collection of instruments in the back of his store! I've been considering an autoharp for some time now, maybe sooner!
