Periscopic Prism Scope

[Valleysniper]

Just a minor clarification from earlier in the thread: IRRC the tube diameter of the PPCo. scopes was not changed, rather some of their mounts were made with enlarged rings to mount 600 or so Aldis No.2 or 3 scopes that were "unattached". Their later Patt.18 scopes were of course smaller in diameter, but never mounted offset as the typical PPCo. and the 600 odd Aldis were.

They were Aldis patterns 3 and 4.
