I always suspected that back in the Great Depression as both Winchester and Remington were working on double barrel designs there was a gentleman's handshake and Winchester went side by side and Remington went over/under. We see the prototype Winchester over/under and Louis Stiennon's patents No. 2,095,297, 2,095,296 and 2,106,416 in Schwing's book and at the Cody Firearms Museum in the BBHC.

Several of C.C. Loomis' patents that were applied to the Model 32, actually picture a side by side, and Dennis Sinita showed me the Loomis prototype side by side at the Remington Museum at Ilion a couple of decades ago.

I wish CSMC would have designed it similar to the Model 21 SxS and put the barrel selector in the trigger rather than in the safety.

I like it. Especially the funeral look of the standard model. Short, though, at 14 3/8" over a 1" pad on a 20ga. No way to lengthen that aesthetically. I'd like 14 3/8" over a hard buttplate; would allow for lots of options on LOP, including the Winchester pad if someone wanted it.

Obviously no one has picked up on what I alluded to in a previous post: it's an Inverness in Winchester get up, with a little differently machined receiver that is blued, and a little different stock design. Plain as day to me, and good marketing by CSMC.

I think hat's what Doverham meant by "...standard Brescia underlug..."

It's a B. Rizzini made to look like a stacked-bbl 21.

It's as American as a bowl of Rigatoni alla Carbonara with a side of Coke.

I hope you're wrong, but suspect you are right; after all, they are still tooled up for the Inverness. Were the innards of the same family (such as the Winchester 101/23), this project would have potential. I doubt the barrels will be of M21 quality either.

I wouldn't worry about the quality of the barrels, GF1. I think the gun will be very nice all the way 'round. Like I've already mentioned, a 20 ga with 32" barrels, upgrade wood and a leather covered pad has got me a thinkin'.

''What is Cyro PatternTM?: This is a trademark process by Connecticut Shotgun Mfg. Co. After the barrel blank is gun drilled and turned, the barrels are put into a very deep freeze. This releases any stress that the metal has endured during the forging. This procedure prevents warping and twisting of the tubes, even after firing multiple shells and reheating the barrels. This is the best method that we have found to make sure the tubes remain perfectly straight.''

Now that is a bucket of advertising shit. Cyro, Cryo or maybe Cyrano de Bergerac?

There are only a few specific ferrous alloys which are PROVEN to benefit from cryo treatments. All of these alloys can contain retained austenite at room temperature, which requires cryo treatment to convert to Martensite. None of these alloys are common "gun" materials.

All other claimed benefits are typically based on testimonials, not on any measurable metallurgical properties.

This from the benchrest shooters website. If anybody knows barrels, they do. If I were to buy one it would not be because the barrels were cryo treated.

John - I'm curious. Why exactly does the combination of a 20 bore and 32" barrels appeal to you? Is it for skeet or clays?
