Any marking on the push safety?
Markings on the front teeth of mag release?
Marking on it Hammer? Op slide? Bolt?
Does the sling have C tip ends?
Markings on oiler?
Markings on any mags?
ETC........
The more you can find the more we can tell you.
A early doglegg hammer could be worth half of what you have in it.
Any Rock Ola or Irwin Pedersen parts = $$
