Hey everyone, I am building a target rifle in 6.5-303 off of a Ross commercial M-10. It is receiving a new heavier barrel, new stock, etc. I would like to make it as close to period-correct as possible, so I am looking for the correct target sights for the rear. I have been looking continuously online for quite some time with no avail. If anyone has a line on one of the following, let me know! Keep in mind they have to be in usable condition so preferably, not too loose.

Parker Hale 9G
Sutherland MkII
Pilblad (any)
BSA Martin
Canadaicon Tool & Specialty Co. (any)
Peddie Parker
Lyman 48 Longslide (150 point) right side

Additionally, for those who have used more than one type, which do you prefer and why?

Thanks for any leads you all can provide!
