I seem to remember a few random thoughts a while back about fitting a soviet pem scope to an enfield, I found a couple of pics of one fitted to a T mount, I think this was on gunbroker a while back. (Century created T)
Its seems there's a few issues causing it to be mounted so far rearwards, the distance between the T mount rings is a bit too wide to fit easily on the scope, about 3/4 inch or so, remembering that the no32 scope has the turrets forward of the front ring. If the PEM tried this the T mount might be too wide to fit between the focus end and the turrets, I'd have to get the calipers across these pictures to measure it up.
This scope is the '1937' model with slightly forward set turrets, another more modern model has mid set turrets and might mount better...
