At my local toy store today, they had taken in
2 Pythons 8 inch 1 blue and 1 nickle
3 Diamondbacks 4 inchers, 1 blue and 2 nickle
1 Model 15-3 4 inch blue
1 Model 67 4 inch early stainless rear sight
1 Model 17 8 3/8 inch blue in presentation case
1 Model 51 3.5 inch blue
All but Model 51 in pristine shape.
I'd never seen that many Diamondbacks at one time.
Also but not from same collection:
1 Model 19-3 4 inch blue
And 3 pristine Browning HiPowers in carrying cases. All 3 had those "long range" adjustable sights and were probably not of vintage manufacture.
