Nice scope, several questions:

1. what is the tube diameter ?
2. where is the Paralax adjustment ? All I see is an elevation adjustment.
3. if this is a typical claw mount, the rings are soldered to the tube and are not easily removed. If they are the tube needs to be "desoldered" and re-blued. (total disassembly). Are yours not soldered on ?
4. what is the reticle ?

The dent and engraving are a shame. It must have had an interesting mount on the drilling as the scope has no windage adjustments.

Thanks !
