I saw some at Farnham in the early 70s. I think that they had replaced the 75 with possibly a 90 mm, as the barrels looked similar to Israeli Shermans.

The Shermans that were used in Canada post WW2 were the M4A2E8- twin GM diesels, late HVSS suspension and the 76mm gun. In Korea the LDSH armoured squadron used the standard M4A3E8 (with Ford V8 engine) from in-theatre US Army stocks. Interestingly, when the squadron initially deployed from Canada it was equipped with the M10 tank destroyer with the 17pdr gun. This was because they expected to encounter Soviet supplied T34 tanks. This never happened and tanks were most often used for close support of infantry, not a good place for the M10 which had an open topped turret and no co-axial or hull mounted MGs. The Israelis upgunned many of their Shermans with a high velocity 75mm gun, and finally with a 105mm gun, both of French design. If memory serves me the French 75mm tank gun was developed from the same gun which equipped the German MkV Panther tank.
