Ruger M77 Extractor Band

Im honestly not sure but I found these parts diagrams on brownells uk

This is the tang safety, it shows part# 48 and is out of stock.

This is the markii and it shows part# 14 and no items are available.

Not sure if its the same manufacturer part# or not but its at least separate brownells numbers. Could still be the same actual part though and its brownells catalog thats wrong. I suspect the only difference is the diameter if there is one.
