PPCo Scope & Mount - Opinions Please

[Roger Payne]

I have a rifle that bears an Aldis with the modified PPCo rings adapted to suit the Aldis scope. (The long lost Bartle mount, perhaps??). These rings bear none of the markings shown on the 'typical' PPCo rings - neither engraved nor stamped serial numbers, nor even an assembly number (assuming the one/two digit number on the end of PPCo type rings is an assembly number) in the usual places. It does, however, bear a stamped rifle number on the dovetail 'flat'.

There are also a couple of PPCo scopes shown; one with the more common 'short cone' ocular housing, & one with the slightly less common 'long cone' type. Both bear engraved serials on the tops of the rings like pretty well all other scopes of this type that I can remember seeing. Similarly they also bear different serials stamped into the one ring end. I admit I find this puzzling - rifle serials stamped into ring ends initially & perhaps if rescoped onto another rifle the new serial was engraved on the top of the rings? It would back up this speculation if someone had a scope with a carrying case that bore two numbers which were also the same two numbers found on the rings, stamped into the end & engraved onto the top. Perhaps worth looking out for??

The loose ring on its own is also a puzzle. It is 'slimmed down' similar to, but not exactly the same as the few other Aldis adapted rings that I have seen, yet the two small locking screws go in from the bottom like in a typical PPCo scope, not into the top of the rings/scope, like on the few complete Aldis bearing examples I've seen. Perhaps an earlier production variant to accommodate the Aldis?? If I ever get round to warming it up & melting out the solder I might be able to get an accurate measurement of the diameter to see if it is exactly one inch, or a little less. It does bear the serial & assembly numbers at each end.

Sorry for the poor quality pictures but they were taken hurriedly on my phone.
