From the advertisement Parabola posted it looks like deliveries of the gun were supposed to start November 1957 & priced @ $125.00.

In the crowd I grew up with that would have been a lot of $$ for a Spanish made or any other single shot with a 3" M12 w/matt rib listing for $121.40 so I would expect the quality to be pretty good but not many buyers.

Does anyone know how long they were produced & numbers sold?
