I must have had some temporary dyslexia last night when I posted😀. I went back and looked at the rifle briefly this afternoon. It does not have many markings (had my reading glasses too!). No 4 MKI is faintly marked in the left side of the receiver, England somewhere in the right. 16991 is the number on the band on the stock. What appears to be Asian writing of some sort is stamped a couple of places, very small.

I'm not hot on buying this one, just trying to educate myself. Thanks for the info so far.
