PPco Scope unknown mount

[Surpmil]

A bolt with no knob; that's a first! And the sling loop on the guard as well.

The mounts are certainly an advance on what was the current at the time, but the funny thing is there is no way of taking up any slop. The Goerz "semi-turret" design which seems to have inspired the front mount, was spring loaded and pivoted up and down. Here, if the user was not careful to keep things aligned when pivoting the scope tube to the right it would not be hard to strain the front mount. The rear dovetail is certainly strong enough to absorb recoil forces and demonstrates a knowledge that they operate in both directions, but there is no means of adjustment for wear.

The folding peep sights are clever; inspired by the Porter on the Ross M10?

So these were presumably the inspiration for the Remington Model 30 that appeared about 1926?

Skiprat, your scope's rear mount has apparently been designed to sit the scope farther forward than the example in Nigel's photos or is that just the length difference between the No.4 Aldis and Patt.18; I forget!?
