wm20 Gearbox main case, inner, battery box and fittings. Oil tank
Gearbox main case, casting # 66-3141, clean and decent. All threads good. $80
Gearbox inner, the one with the speedo drive, has a tiny crack, but has some of the gear change bits. $25
Battery box and all the fittings (both back plates) original. $80
Oil tank, good condition, stripped of paint so you can see it is sound. $80
Pictures if interested.
Full disclosure: The battery box and oil tank came from Bastiaan a while ago, but I discovered an even better example of each!
I'm in the USA (Boston)
As I say, pictures are available. I just don't have any luck loading them here.
