An interesting scope combo.

I see your point!

Begs the question: how deeply recessed is the objective lens? Would a shade be necessary? I'm guessing it would.

Something similar a little larger would probably have made a good replacement for the No32.

In "Without Warning" pps. 65-71 the trials are detailed which led to the adoption of the E. Leitz Canada "Sniper Scope C1" in 1959. One of the sights included in the trial was a "UK 3x Type 1956"; anyone know what those were?

By way or comparison the Soviet PSO-1 came out in the early 1960s with a range-finding illuminated reticule, IR detector and zero-retaining quick release mounts.
