Long branch No. 4T scope help

[ncozzo]

My mistake the screws are flat.

I want to apologize for being a pain with all the questions but I am trying to learn and educate myself.

Since the R.E.L. MkIII is actually the correct scope would I be better off going with a cheaper British scope instead of the Canadian MkII? What are the odds of actually finding the MkIII? Should I just be content with having a Canadian scope?

***Not sure if it matters but I did just find out that the MKII is a 1945 production same year as the rifle.***

Also as a side note neither the transit case or the scope mount have a any numbers on them. The case has spots for rifle number and scope number but they are empty. The scope mount doesn't strike me as a repro because the guy I bought it from said his father had it for a very long time and the old weaver scope that was mounted on it when I bought it would corroborate that story.
