WW2 Era 1942 Dated Tank Periscope – Unidentified

This periscope is well marked to the front with ‘Part No C.I.A. (T) 9365 W&S Ltd 1942 No 68843’, I have not been able to identify to which particular tank this belongs but as it does not have a crow foot mark I am thinking it is not for a British tank. It comes in good but used condition and measures 8.75 inches long.
