Help Identify Vintage Optic

[PNW Skipper]

This vintage scope reminds me of a Fecker scope with the mounts and the mid-barrel focus adjustment, but the scope is completely unmarked and the adjusting ring is very different than those on Fecker scopes. I understand that there were some externally adjusted scopes made in the UK, but am not familiar with the makers. Can anyone help identify this scope? Thanks!

Reminds me of a 3x Diana scope with the mount adjusting. Looks better than those though. Bump for you
