Apologies to those who have seen this on another forum already!
Inspired by Hector Martinez's posts on aperture sight enhancements, I rummaged though my drawer of sight gadgetry yesterday and came up with this:
1. Classic HW 35L from the 1970's
2. Special Williams "ARH 624" sight, made for the old Weihrauch 13 mm scope grooves
3. Gehmann US-to-German eyepiece adapter bushing
4. AOS fresnel lens unit to sharpen view of the front sight
5. Gehmann German-to-Parker Hale eyepiece adapter bushing
6. Parker Hale "Iris" eyepiece. This has a sliding multi-leaf-type adjustable opening similar to German designs, combined with a rotating disc with 5 colored filters
7. Parker Hale PH 62 eyeshade. No cheapie piece of snap-on molded rubber here, but proper milled blued steel with a matte phosphate finish on the back face, threaded into the eyepiece housing.
And...it works! I was able to crank open the iris all the way for a great bright view, and still see both target and front globe clearly.
This was kinda silly of course (I coulda just put a Gehmann iris in the AOS and saved a few layers, LOL), but was fun. And, I think, shows the value of the AOS unit when properly applied, and of the inexpensive adapter bushings. The US-to-German one will let you use one Gehmann or Centra iris on about any aperture sight you're likely to ever own.
