'My forks are (I'm 99% sure) 1959/1960 internally sprung 3TA/5TA.' That 1% that gets you every time! If I had gone to the supplement in the back of my spares list I'd have seen the section on T20S. These forks are almost identical to 3TA/5TA forks except for the stanchions. Does anyone know if there are any dimensional difference between a T20S stanchion (97-1280) and a 3TA/5TA stanchion (97-1123). As they both use the same top yoke, restrictor rod, bushes and springs I don't see how there could be. If not would I be able to use the 3TA/5TA stanchions as they seem to be easier to get hold of.

I've done a bit more investigation and have been able to answer my own question. My forks are (I'm 99% sure) 1959/1960 internally sprung 3TA/5TA. What has been confusing me is that they seem to have none standard stanchions, none standard drain plugs and have been reassembled incorrectly some time in the past (the upper guide rods are not attached to the cap nuts)!

Can anyone help me? I've recently bought a 1959 cub, nominally it's a T20C but there seems to be very little of the original bike left! The forks need some attention and I'm trying to identify them. I am sure they are HW and off a nacelle faired model 3TA/5TA. The springs are internal but the stanchions do not have fill holes at the top as they should according to the manual I downloaded. Can anyone tell me if there is more than 1 model of internally sprung HW telescopic forks?
