Are you saying that the AN was introduced into our service in '77 Gil? WELL before that...... We had those in the late 60's/vietnam era and you might recall that they were zeroed in on the base as opposed to the RankPrecision RP-SS20/L1 IIW that zeroed internally. The big AN2's sights were taught at first and then when the RP SS20's came on stream the AN's were phased out. THey both fitted onto the same side mounted L1A1 rifle top cover but the additional 'intermediate' mount on the AN made it a bit side-heavy.

I have the instructional dates handy too.

At Shrivenham, we played around with a black plastic insert that you could press into the OG lend housing with a tiny stop-down hole so that you could use them in a daylight classroom. Later, this tiny stop-down hole idea was incorporated into the rubber OG lens protector that had the words DO NOT OPEN IN DAYLIGHT embossed across the front

As for the SUIT sight. I see where you're coming from Charlie and it was a good effort at making a self contained prismatic fixed focus rifle telescope AND lead the way for the VERY good, tough and hardy SUSAT. But the mounting was absolute crap, as were the pure Alice in Wonderland range callibrations alluded to by that lever. If you can move the sight on the mount, then guess what? It WILL move

There was a better low light target acquisition device in the early 70's and that was the big 7x 50 Artillery binos. Mind you, better things were on the way - like the big SS20/L1 IIW's The thing about giving one person that night vision ability is that only he can see what he's looking at! And if he's giving the fire orders it's going to spell trouble...........

Maybe I should tone down my views of the SUIT and say that while it's not quite crap, it's, maybe in the shxxe arena! A mickey mouse watch maybe.......
