I am bidding on a BSA Martini-type .22 with a tang sight. There is a large notch on the barrel for a missing rear sight. Assuming the barrel is up to serious competition, what would the hot stove league recommend in the way of optical sights for this rifle? It's a take down model, 33,000 range SN. What finish did this rifle carry new? Remember the black paint army surplus stores used to put on all manner of military equipment? That's what it has, flaking off in spots. Surely that's not the original finish. Haven't received it yet, so don't know if the receiver is steel or not. Blue? Parkerize? Appreciate any knowledge or suggestions.

They were blued steel actions.
There were a number of different small model or Cadet actions.
There is also the BSA Martini International series of rifles.

Here is a link showing the Small Action Models:

The rifles frequently had either BSA or Parker Hale sights.

I agree that rifleman uk website is the best.
