Milbro G31 peep sight

[colbymog]

Hi All,

I have a Diana G44 which has most of a Milbro G31 peep sight on it. I am missing the eyepiece/aperture that screws into the rear of the sight.

Does anyone know where I can get hold of the eyepiece/aperture? If not does anyone know what thread type and size this should be and the rough dimensions? I have never seen one so don't know if the hole in the aperture was fixed or adjustable.

As always any advice gratefully received.

Regards

Andy

I have one of these olds sights complete, box, rubber eye cup, the lot.

Got it off the bay about a year ago for about £8! (Im not joking. all in all it cost me around £12 to get it home). Good condition apart from the rubber cup has a split and stinks of smoke! It is just sat in my workbench.
After seeing this thread I took it out, unscrewed the eyepiece and it fell on the floor! Took me 10 mins to find the bugger.....

I can send you images of it if you want?

Yes please that would be very helpful.

Ped just wanted to say thanks for taking the time to measure it for me. I know what the lathe will be doing this weekend.

Here are all the images I have of the sight. Some of them are of the eye piece by itself.
