Millett adjustable sight

[dtippie1]

I have a question. I read a while back that someone had an older Browning HiPower made in the early 1980s with the old style Adjustable sights. They had replaced the old rear adjustable sight with a Millett adjustable sight that was able to use the old front sight and the existing rear dovetail. Does anyone know which Millett sight that it was?

Thanks
