the phoshate used By Remington is Zinc Phoshate..light grey..
that info came from the man who was a manager at Remington during the time they made 1903A3,s and A4,s.
he lives in Fort Collins Co.
iv learned in the past..to never say never, even with scopes..
but.
what i stated about Kollmorgan, is a fact, on its production of scopes. and spot of with the dates.
Weaver M73-B1 would be the original scope used on that rifle,
Lyman AK variants.
M84, Libby glass company made.
and a stretch for the Weaver K4-60B would be acceptable for a 50,s vintage replacement.
id almost agree with the use of a Kollmorgan with target turrets.
great scopes, and just an early Redfield in my book..most the rifles i own have Redfield glass on them.
but the facts are...the scope thats installed on the pictured A4, is not likely a military scope..
and im ok if you dont agree...its your rifle, and you should like it just the way it is.
