The 40mm Bofors was manufactured in some quantity in Canada at Otis Fensom Elevator Works. The Canadian versions were the simplified carriage with the fixed barrel travel lock mounted on the rear axle housing. Most ended the war with shields fitted and Stiffkey (pronounced Stoo-key) sight. See the photo I posted in "the Sergeants' Mess". The sight was named for the Anti-Aircraft School at Stiffkey where, I believe, it was developed.

Is this the "Stiffkey-Stick" AKA "Correctional Sight" type sight?
The US used a "Kerrison Predictor". What did that look like?
Picture from Holland December 1944.
Added after that I became wiser: Yes, this is the Mk IV Sight aka Stiffkey-Stick. Introduced in 1944.
