This shows the original safety and bolt.

This is how my pre-war M70 target rifle is configured.
I have a pre-war sporter, but someone has had a late model safety and bolt plug installed.
The early Lyman 48 sights required a cutout in the stock for mounting
For RCS:
Your rifle is configured for the last model safety though I believe that it is an early post-WWII rifle. It has the "clover leaf" top tang so may be pre-WWII. My sporter has the same type of safety.
Here is another commercial safety for the M70 by Pachmayr. Looks as if Winchester may have copied this one.
This picture also shows the early bolt. From the December 1937 American Rifleman.
