Sorry to hear of your woes mate
Do you have any recourse from the seller?,,,private sale ..or Dealer???
I guess I've been quite lucky in the few (about 8) 1920-30's sxs guns I've had in the last decade or so..only one disaster
And that was the most beautiful 1904 Francotte 14 or more likely 18e ...But thanks to Abe Chaber I got my cash back.
Have you contacted the seller at all?...or is it way to late???
good luck
Franc
