Can't help on values except discriminating shooters know SKB in all iterations are reliables, best buys, and yours in class of its own. My Model 500 o/u 20ga vr sst via Mitsui is common by comparison but same tolerances and finish bought for $CAN180 I think in late 70s worth now considerably more. It's also my go-to gun. IC/M does everything for me from grouse to geese.
