I have one on an early action. It is blued and has the formed sheetmetal trigger guard, manually engaged safety. The one on GunBroker is in a later action, I like to see all the markings on it to see if they match. The assembly stamps on the barrel and receiver of mine match and it has a Stevens inspection mark of the number 20 in a circle which is often found on '30's vintage guns. All the markings are consistent with guns made at Chicopee Falls, which is where I think all these were made.
Bore is offset lower to work with a standard firing pin location.

24hourcampfire/895524The stock on mine had been cut off quite short and I thought it would be easy to find a replacement, not so, a couple I've tried do not fit well to the receiver. I found that the receiver to stock fit is a little different on the early receiver, so later stocks do not fit very well. Here are stocks swapped with a later 220 -

I think Savage experimented with 22 SHOT for a time in the. There is at least one Model 6 in 22 SHOT, I think it's probably a one of a kind R&D gun -
Model 6 22 SHOT The price listed is without the added 20% premium.
I requested more pictures and the bolt in it is milled down to lighten it so it could cycle with the lighter recoiling shot cartridges, I don't know if that worked though, you do not see semi-autos in 22 SHOT, there was one company that tried that, but I do not think they functioned reliably.
I have a factory barrel for a Model 5 bolt action in 22 SHOT -
Both barrels are counterbored larger at the muzzle.
My barrels only has the patent for the Model 5 stamped on it, the Model 6 linked to above has that patent, which still covers some of the semi-auto design, plus "OTHERS PENDING" under it which is correct for early Model 6's.
