[jon foz]

First is the MX seat



secondly these Shimano cranks,marked up as "600"





They are currently on my Torker,was thinking of having a swap around,but not quite sure on their age

As a guess, crank 83? Seat 82/83? Might be later?

Date should be on the bottom of the seat, I would guess at 81/82 same for the cranks 

[fouronethreeoh!]

Shimano has a date code, two letters, something like HF. Should be on the back of the arms. First letter is year, second month, and they started counting years from A in 1977.

i've put a shimano date code finder up in the stickies somewhere i think.
