Grab this Crosman Model # 1 this morning at a local country flea market. It's not mint but does hold air and shoots, I couldn't be happier with my $90.00 investment.
No this is my first. I have seen them for sale on the bay, but never pulled the trigger. Today was just a matter of being at the right place at the right time. Think I'll take it to the Midwest show next weekend.
BSA Stutzen uses the same basic Williams sight but the base ramp, which is part of their dovetail rail, slides in the other direction. In fact, I think it looks better that way. You can find different blades on eBay. Search: Williams WGOS
