I noticed Winchester Model 21 serial number 79 for sale at the Spokane Fair Grounds Gun show today.

It would be interesting to see what the patterns look like with those bell chokes. They were somewhat popular when shells were paper and wads were cork & felt. I have a WS-1 / WS-2 Model 21, but never measured the chokes.

Seems as I expected the ws1/ws2 is a common configuration. That is why I was asking has any one seen the ws1/ws1 like mine. Interesting choke for sure.

I have seen other 21's with ws1 and ws1 but most have ws1 and ws2

I've seen other Model 21's that had both barrels bored and marked WS-1. You could order them however you wanted them. Your gun is correct but a Cody letter would,confirm it for sure.
