The insterted "C" designation usually meant a modification proposed by REL and accepted by the military authorities, so I am led to believe.

#33 was used on tanks with the 2 pound gun..the C #39 scope was used on the tanks with the 6 pound gun..This could have been in a Ram tank with a 2 pound gun that was up graded to a 6 Pound gun..the original scope was kept and re calibrated and reused in the same tank with the new 6 pound gun..or some such scenario..
But the scope is just an upgrade from a two pound to a 6 pound gun application..re calibrated and re stamped to signify same..
A true piece of history.
