Crosman #411 peep set?

[SwampHunter]

I just purchased a set of these and can't find any info on them. Does anyone know when they were made or what they were made for? I'm not sure if they were made for a specific rifle or if they were simply a crosman aftermarket sight option?

Found this on an old auction sight..

Crosman Match Sights model 411. Peep receiver sight, click adjustable, clamps onto scope grooves. Some minor scratches in clamp area. Globe front with 3 interchangeable aperatures .109 - .125 - .141 . Fits crosman models 66, 2100, 2180, 2200 and model 1.

I've used these on other Crosmans like the 760.

Thank you,  that was more than I could find on them lol, just doesn't seem to be much info on them available. Good news for me, will be an excuse to buy a 2200 if they won't fit anything else lol
