Just found this one at auction. These are very hard to find.

RARE WWI ALEX MARTIN GALILEAN SIGHT

That's one of our own with the current highest bid.

For what I know it consists of two parts, so the rear lense would be missing.

Seems like I won it. Now to find the proper rear sight.

That's the situation I'm in with my Neill sights. Got a front sight but nary a rear to be found.

Cool, good job on winning the auction!

Thankfully the Martin rear sight appears to be a standard No 9 sight with a lense inserted. No machining needed. I hope...

I found this comment "Aiming points aside, Galilean sights had their fair share of idiosyncrasies. Firstly, focus was adjusted by the convex objective lens. The light passing from the target, through the objective converges on the concave ocular, there it is focused into parallel beams, and enters the eye. However, the concave lens is not actually required, and an image can be formed by using a small aperture, analogous to the way a pinhole camera forms an image."

With any luck I can use it without the rear lense.
I'm not sure if that helps with other Galilean systems though.

Winning an auction is the easy part. Finding the money to pay for an unwise bid is somewhat harder. LOL.

I have the beginnings of an idea about adding a lense to a normal rear diopter sight.
