Yes, when I sold mine to a friend, he gave me $1500cdn for the Johnstone, an M1Thompson and an M1 carbine...that was about 1990 I think. Low but do-able...sad. Now the Johnstone alone would be about $5/6000CDN if you're willing to take the chance with our Gubm'nt.
Maybe it was my old one. Caved the left rim right in, then the outside edge of the mouth against the receiver.
