I'm guessing cutting the lower leg in half and counting the rings won't work, so is there a simple way of establishing how old my forks are?
I've 2 pairs of revelations, and am pretty sure I know how old one pair is (as I bought them!) The 2nd pair came on a 2nd hand bike I purchased, and I have no idea what kit I need to give them a service.
One set is a "Revelation Team U turn" 120-150mm, which I think is of '10 vintage:

The other set is labled "426" and measures 140mm:
