Model 220L shotgun parts HELP

[Vasbyt45]

So far noone has been able to provide a complete schematic online of the old 220L 410 Savage. I did find a couple gun parts suppliers but their diagrams dont list the spring I'm looking for. Below is a couple pics of the spring in question, maybe you old school guys can help me. It's either the cocking spring or the load/safety spring. I don't know if it is included with the part that it is attached too(and this is why I cannot locate it) or if it is separate. Rather difficult to describe but let me try, it's U shaped and at the U ends the spring becomes coiled 3 times(as it fits over the cock/hammer and then ends in 1/2 inch straight pins that hook behind the trigger mechanism to allow the spring to function(spring).

Any help appreciated, trying to repair this shotgun and hand it down to my son, it was my grandfathers.

I've got an exploded view of the 220L but theres 4 U shaped springs shown in it, can't tell which one you need from the small pics you posted.

Most of the marks you mentioned are all assembly marks except for the SP in the circle, it's a proof mark.
