I've been using the Numerich schematic as a guide, hopefully that's a good idea.

Luckily the fore-end pieces are all there and still together.  And I am learning alot day by day.  It is needing a complete rebuild, including barrel rib and re-bluing.  The stock and fore-end wood furniture have been replaced and I have a wood worker friend who is going to stain/linseed oil them for me.  I started out needing about 25 parts for the receiver and I'm down to 8 over the past two weeks.  So I'm sure these 8 will take forever or a trip to CSMC.  Placed at call for Mark at Wyoming Armory, he's out until tomorrow so I will be following up.

Connecticut Shotgun Manufacturing Company bought all the tangible and intangible Model 21 assets from Winchester-Western, including the exclusive rights to make the gun and parts of the gun, and to mark it with the Winchester brand. As you doubtless already know, they don't sell parts. 

I don't think they could make the exclusive rights to make the parts stick but your real problem is finding somebody who knows the gun well enough to make and fit them. 

CSMC is not cheap but they do excellent work and- very important -- will warrant everything they do. 

Before you decide what to do, however, I really suggest you speak to Mark at Wyoming Armory in Cody. He's a WACA member and one of us in spirit. I believe WA has worked on 21s before and I would discuss the matter with him.at length. He may not be able to help you but if anybody can offer suggestions, it would be Mark. Just Google the Web for Wyoming Armory. 

Lots of M21 parts on eBay

Quite frankly, your only options are to find a knowledgeable & talented gun smith who can make the parts you need, or send the gun to CSMC.

I'm new to the Model 21 world.  My son and I purchased a Model 21 basket case as a father son project.  The gun has a low serial number it seems to be from 1930.  I've been scouring the web for the various parts for my 12 gauge, single trigger, manual safety model.  I'm been through Numerich, Jacks, ebay, gunbroker, and the folks mentioned on Winchester Repeating Arms obsolete page, etc.  Mostly I'm missing some of the small pins, timing weight parts, and shift lever button.  I'm heard about/called CSMC and hopefully won't have to go that route.  I understand this is a pricey piece of equipment though.  Does anyone have any advice for where I might be able to find some of these parts?

Thanks for the information Bert.

I'm one for having tings as original as possible, so I'll be looking for the grooved slide handle (3 screw).
  

Those are almost impossible to find (original) as it was the weak (most often found broken) piece on the early production Model 1897 shotguns.  All too often they cracked right at the escutcheon screws.

Model 1897 s/n 82444 was manufactured in September 1899.

I think it has an incorrect slide handle. Comparatively huge compared to the grooved style. It doesn't look like it belongs on this gun. 

Any input on both would be very helpful. (Sorry, can't figure out how to upload a pic)

I had a lot of experience with a straight cylinder barrel on a 12 gauge Auto-5. With quality #7.5 trap loads it shot nice 50% 40 yard patterns. 

If the cracks were inadequately repaired, best to find that out now rather than on a hunt.  Then you'll have time to do or have done any necessary work and test it, before Fall. 

Don't worry too much about wood repairs. The adhesives available today are so good that, if the joint is prepared properly and the product is used as directed, you won't have to deal with it again no matter how many short magnums you put through the gun. 

If you are not a craftsman accustomed to working with wood, reading labels, and taking your time, turn the work over to a reputable gunsmith. The fee is usually modest. What you've got is a very nice gun that can last generations but a bad DIY job can eadily condemn it to becoming s parts source.

I just recently purchased myself a vintage Winchester Model 12 shotgun and I wanted to come make a post asking the experts on what I have. I'm personally new to this world of vintage shotguns so I honestly don't really know what I have here besides it is old and a 12 gauge. Anyways, in the auction post it listed this shotgun as a 1920 Model 12 CYL bore with a 26" barrel. The gun looks and feels honest, worn but still completely functional, I've already been able to take it to the range no issues. My question for you guys is what do I really have on my hands here? Is it all original or rare? I got it for an honest price and I didn't buy this to flip but to enjoy. I want to know if I have a real survivor here or just a shooter. Open to all comments and suggestions!!
