Hi Ernesto,
Next time I pull of the scope, I'll take some photo's.

I have some photo's of an apeture sight from Gunbroker from about a year ago but I have not yet worked out how to post images on this board yet and I don't have my own website.I'm happy to email them to you if you like. However you cannot see the plunger button in these photo's. The seller wanted $US250 and I was seriously thinking about it when I found the main part of one locally. I only had the smaller parts made up and I think if you wanted to get the complete sight manufactured it would cost too much. I'll check with Tilleyman if he has all the drawings.

Good luck with it, I'll keep an eye out for another one as well.

Does anyone have an easy way of uploading images?

Regards

George
