Hi Neillll (let's make it four ls)
It's a bit hard for me to follow, but a good start would be to look in the Gallery & archive section, there's one RinglÃ© catalog (94 i think, not sure). Another source could be this http://www.firstflightbikes.com/vintage.htm
it's a timeline year per yaer with a list of some of the components available that year, it already helped me.
Third, when RinglÃ© is written Italic and laser etched it's more recent (no idea of date though) than the one with straight letters and written with stickers.
To be complete (with what I know) Sun RinglÃ© is even more recent (after RinglÃ© was bought by Sun) and has little to do whith the old RinglÃ© parts we hate/love (depending on the direction of the wind).
Not much help, but a start.
