I recently purchased a package deal of 2 No4 sporterised rifles with full length barrels.
One is a savage no4mk1* with 2 groove barrel that had the bayonet lugs removed, barrel polished and blued and weaver TO-1 mount installed. It’s a shame because everything on the rifle is correct, all savage parts and magazine.

The other is the head scratcher. It is a Britishicon made No4mk1 (not mk1*) with intact full length 5 groove barrel. It has certainly seen an FTR at some point. There is a faint British serial number on the wrist and a pronounced Savage serial stamped over top of it.
There is a broad arrow and 1942 stamped just below the safety.
Oh and there is a bizarre star stamped on the top of the Knox.

What’s with the savage serial number??

Any info on what I’m looking at is greatly appreciated!
