I've read that the 22C could also have been used with the 25pdr so the production of this sight wouldn't have been limited to Ram II production numbers. My 22C has a serial number of 9980-C. There are no markings on the focal plane other than "L", "R", and 4 graticules on the horizontal line. I also have the P37 webbing made for the sight to protect the eyepieces when the sight isn't mounted suggesting that it might have been common for the sight to be stored elsewhere than on it's tank, howitzer, or gun. Derek.

Looking through my No.22C MkII, R.E.L., 1942, 6699-C, I can see the slight magnification. It is specified in a manual on using the 25 Pdr. as an AT gun that I have a copy of dated 1942, along with the No.29 sight. The eye relief is about 3" at full field of view. This is the sight that is noted as giving 6 Pdr. gun layers black eyes in North Africa. There doesn't seem to have any any kind of rubber eye cup provided. I assume the reversed R and L on the crosshairs were to help the gunner lead a crossing target by referring to the direction of travel. Presumably the design was an expedient. One wonders why the No.24 sight for the 2 Pdr. was not modified to fit as the guns were practically useless and the No.24 looks much larger and more suitable - it even has a rubber eye cup!

Gentlemen,

I have two telescopes that may suit your needs far more than mine, should anyone be interested. They belonged to a friend of mine who has passed, and were amongst his "collection" of odds and ends.

Both are "new" in the box, marked with Telescope, Sighting, No. 22 Mk II REL(C) 1942. The boxes appear to be original as they are marked with that same information, although they do not appear so yellowed as to have been made in 1942 (I could be wrong as they have been stored out of light).

I am located in the Southwest portion of the U.S.A. and can be reached via P.M. or by phone 915-494-1892

British Sighting Telescopes

Below is a listing of sighting telescopes used in British tanks and Artillery, the list is probably not complete as there are so many variants were there is little or no data available.

Ron ..
According to the chart I just listed the scopes you have would have been used on the early 6 pounder anti tank..gun..or mounted early 6 pounder gun/..No. 22 Mk II REL(C) 1942.

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.
