An old thread I know, but as put up back in 2014 on this forum, the following is from a publication "4E 1st February 1968 Product Information"
"The RX casting is a bit of mystery, but we have noted that there is a change in the valve threaded port in so far as the seal and washer arrangement is concerned. RX shows on all of the lever product castings, and by assessing the date codes, seems to have been started around 1964 or so.
There's a myth that floats around every few years that the RX means rebuilt, but it's real hard to retroactively cast letters into a body. Also, you'll find some models of lever shocks in Bronze. It is indicative of piston size and applies to the tube shocks as well.
The natural body and painted (Parkerized?) arms would seem to be the way the shocks were delivered to the assembly plants. Often rears were then fully painted over "on the line", but that's conjecture from some assembly line photos, and may not be consistent."
Cheers... Gareth J
