Ok I'm a lucky fella. All cleaned up already. Thanks to either Robby Beck or Gary Beal (the previous two owners) it had already been stripped down and cleaned and re-greased with white lithium so it was easy as. I probably didnt need to go all the way but I dismantled it fully anyway to give it a good clean up. Although it has been about 5 years since I got it
Tomorrow night the regrease and reassemble.
