Pipe ID

Trying to narrow down a maker on these. The cord guide and the flat bottom stocks seem to have a Glen influence but the unique (I think) characteristic is the ferrules being marginally smaller than the drone side wall?? Is this a characteristic of any maker, or are they machined to accept both imitation and faux ivory mounts as well as nickel and this is the result?

Thanks

I get a CE Kron vibe from this, but I couldn't really tell you why.
