History of Winchester 32 Gauge Shotgun?

first of all I've never heard of Winchester's involvement in 32 gauge shotguns in any way so I'm just referring to the "32 gauge" & the ones i currently own & shoot.

I'm looking for more info too. I now own 2 of these 32 gauges, an American arms 32 GA o/u & a tecni-mec, a rizzini co. Made in Italy 32 GA o/u. Having owned the tecni-mec since 1990, it has become my favorite dove, quail & chukkar gun as well as for younger pheasant.

I have just commissioned the main rizzini company in Italy to custom build a set of 32 GA o/u barrels to fit my existing rizzini "small gauges combo" set of 28 & .410 GA barrels on a 28 GA frame & should have it mid 2012.

The only ammo maker i know of is fiocchi who also makes 24 gauge shells. #6 & #8 shot can be had in a 2 1/2" shell with 1/2 oz of shot.

Even though this almost exactly a 2 1/2" .410 load for some reason i can shoot the 32 much better than a .410 or 28, even equalling many of the 20 GA scores i have shot as have others who have used it.

That's all i know for now...about the 32 GA shotgun!
