Sporting Clays Classic choke tubes
 

For those that own or have an interest in a Parker Reproduction Sporting Clays Classic you'll see noted on the back of this brochure and shown as well in The Parker Story, that Skeet I and Skeet II choke tubes were included with the six choke tubes originally supplied with the gun. Have you ever seen a Winchoke choke tube with Skeet I or Skeet II designations?

Not that I recall but I will look when I get back to CT from MD.

If yours are like mine George they'll be stamped "12-S". 12-S measures .003 of constriction in my guns, this of course corresponds to a Skeet I designation. The noting of the Skeet II designation remains the mystery . . .

The six choke tubes in the gun and case are marked F, IM, M, IC and (2) are marked S.
I’ll check my son’s SCC tomorrow. The cokes are as you probably know marked with notches so you can see what’s in the barrel without unscrewing the tube.
