You best move would be to get a copy of the Gun Digest Firearms Assembly/Disassembly manual for shotguns, available through Amazon.com among other sources.
Get a copy of the Gun Digest Shotgun Assembly/Disassembly manual. It should have the Mod 67.
You can find instructions for assembly of the 300/900 series at the URL below... you might be able to figure out disassembly from that. http://stevespages.com/pdf/ithaca_300xl.pdf Doug This link is for disassembly of the XL models which are gas operated. Mine is just a model 900 and it is recoil operated. I am still trying to figure out how to get the charging handle off my Ithaca 900.
Best left to a factory trained gunsmith
The Savage No.94C was apart of the Model 94 series shotguns that were made from 1926-1945.
Pull on the front of the forearm it will come apart from the barrels......then break open the shotgun (like you were going to load it and the barrels will come apart from the reciever.
I was looking at this model tonight and the owner took the gun apart and turned the small righ around that the spring pushes against.
You can request an owner's manual for free at the Remington website.
. to remove the bolt on this model you must lower the tube assembly,there is a screw under the stock, remove stock first.
You should be able to find a assembly-disassembly guide for your Winchester model 37 on E-bay.If not you may to need to visit a qualified gunsmith.
You can get the manual from this page with some basic info. http://www.winchesterguns.com/services/index.asp
If you took it apart without an owner's manual and now can't get it back together, find a gunsmith.
There are many Youtube videos showing the disassembly and reassembly of the Mossberg 500, which is the same gun, more or less. I took my M550ar apart tonight to replace the forearm, and I used youtube as a reference. The forearm on the Mossberg used two slides and the Westernfield only uses one, but every other part of the assembly is about the same with only minor differences.
