OK, i might have been a bit over the top there. I only have 7 flight rings.  5 of them have the double lip, 2 have the single lip.

Im sure some flightrings have a different size "ring" and it was thickened up on later ones but Ive not checked my ones yet. Lots of them are on bikes so its not easy to put them side by side.

not sure about the machining but measure the centre hole as i'm sure some of the later one's didn't need a top hat washer as they were 19mm

Non of mine need a top hat washer, they all have a 19mm hole. Thats the main reason i used flight rings, I didnt (& dont) like top hat washers.

They are all still the early font, so they defo aint mid 90s ones. There were big changed in flight rings when they tried to make them stronger. There was a bulge where the crank arm bolt goes, and the cutouts were smaller
