1942 WWII Canadian Churchill tank gunsight

writings on the sight says TELESCOPE, SIGHTING NO 31(?), MARK I(S)

sight picture is very clear, 1.9x zoom. “6P and gun” on the left side, MG on the right. Hard to take a good picture with cellphone because of the rubber eye-cover.

It should be for 3” howizer in A.22 Churchill tank hull

Pickup in GTA is preferred, so you can have a look in person. Can ship on buyer’s $.
