Canadian Navy scope

[killa]

Anyone here know anything about these?
Value ....rarity...etc?

 

[woodchopper]

not for a small gun,

I'm guessing its more for something that has a caliber measured in inches, several inches

 

[NavyShooter]

Probably WWII era....likely for a 3-5" gun.

Looks pretty cool, sorry can't help with identification.

 

[RobSmith]

I'm going to hazard a guess and say sighting system for a 5 inch gun ?
