Irvin, In my observations price is far more relative to condition, features, gauge, and grade. I consider production timeframe just another feature. Personally I think the later single sight plane rib makes an already not graceful featherweight frame even uglier. I don't care for the squarish forends with wood proud of metal found on the later guns either. However I sold a late 20 ga ideal for twice what I sold an early one, but the conditon was relative.
