Delighted to see this thread revisited and more information exchanged.......

Seeing this made me recall measurements I have taken over the years on vintage Model 32 Remington SKEET guns. Certainly one of the biggest winners in early Skeet circles right from its introduction until decades after its demise post WW II.

Like the Ithaca skeet chokes, I recall that the 32's chokes had two different bore diameters , and both had the flared section at the muzzle.

As another interesting note the Bottom or Skeet "out" bore was tighter than the Top barrel's Skeet "IN" boring.

I'm off to the vaults to dig out the only two examples I still have....I'll get the micrometer out and carefully record my findings, but I recall that both these and previous ones have had very closely matched internal dimensions.
