Owners manual & schematic for a savage 220a, 12 gauge shotgun

I am a Member of a VFW post that does Shotgun Shoots. We recently received an old Savage 220A, 12 Gauge single shot hammerless as a donation for our shoots. The Gun works Fantastically, but it needs a little maintenance and Cleaning and it may need a new Firing Pin Spring, BUT I can not find a Schematic or Owners Manual anywhere.. I can Probably take photo's myself as I disassemble it (done that many times over the years), but looking at a Schematic & Manual would be easier!!
If anyone knows where I can locate; 1. parts info, 2. A Schematic and 3. An Owners manual for a SAVAGE 220A, 12 GAUGE HAMMERLESS, SINGLE, that was made in CHICOPEE FALLS, MASS.. (The old plant) please email me at; alansmithee100@yahoo.com ..
(p.s. If anyone can kinda give a little date info, that would be great too..)
Thanks for any & all replys.. Much Appreciated for all help!!

Chicopee Falls stamping puts the production date somewhere between 1946 and 1960. You'll be hard pressed to find an owners manual as the 220 hammerless design was made between 1938 and 1965, and being a basic utility gun they generally weren't well cared for or kept after. Best bet to find a schematic and parts would be Numrick's Gun Parts.
