Help with an Old savage left hand 30-06 last 3 digits of serial # 056 with the heaviest trigger I've ever felt, that MUST come off the rifle.

I can't find a trigger to fit. I have got as far as the Sav-1 and it wasn't even close to fitting.

I have some pictures but can't figure out how to post them here. I can Email them to you if they might help. spurgear77@hotmail.com

Is there anyone who has experience with a savage this old?

is there a code to figure out what year this receiver was made?

Thanks- Dave
