LF Marlin model 120 Magnum parts

[Huntsman]

I'm in search of two springs and two detents for the safety,
The owner tells me that all that is stamped on the bbl is 120 Magnum so I am only assuming that it is a Marlin. All I have to work with is the shotgun minus the bbl which is in Sask.
Thanks in advance
