Help ID this front sight

[Trebor Snave]

I'm looking for some help identifying this front sight. It's got a mating collar that fits on the barrel (not shown) that indexes it in case of removal. Obviously there's a bubble level on top and it takes a 22mm iris, and it fits a 0.750" barrel. The locking collar on the front is loosened to adjust the sight body up and down, and the markings are only on the opposite side.

Any ideas?

Looks like an RPA that was sold by OK Weber years ago

Pretty sure that is an RPA. I only see the tall version on their web site now but this would be a standard height.

Thanks gents! I seemed to recall that it was an English manufacturer but couldn't remember for sure.
