Nope never been that lucky .
I did do a remodel for an elderly lady about #5 years after the 68 GCA ,only to be offered a 1926 Thompson her husband had owned .
So I called a close Friend who was a dealer and he bought it DIRT CHEAP !. Was standing in his shop some years later when a older Gal walked in with a muzzle loader ,she wanted to sell . Turns out her Grandfather had that Rifle up until his demise and it was passed down from his Grandfather . Was an 1840's Hawken's rifle . Never saw My Friend so excited in his life , as he collected them it was a spectacular Rifle in Excellent condition .
The only Great deal time in MY life was when I was offered a 1956 Chevy # 2 door with Continental kit from the original owner ,it had 14,386 miles on it . She was the neighbor lady to the Thompson owner and sold it to ME for EXACTLY what she bought it new for . Sales owners book and original dealers key chain included . THAT WAS A BARGAIN BUY
