HW/Weihrauch Stainless HW guys

A friend of mine asked me for a front Gehmann adjustable aperture, he is 75 years old and still shoots seriously at 10m, I couldn't say no to him. The rear color diaphragm and diopter are on my HW30, I will not part with such a set until the day I die. The whole set cost $286 then, which is half the real price. I think real price is about 650.There was a thread about this sale on the forum.
I think I recall discussion now that you've jogged my memory. I did buy the Gehmann sight from a member at what I thought was a great buy. It's an absolutely fantastic piece.
