Got it running on positions 2 to 5 low to full speed with right sort of

but pos 1 has problems. I used a variac of course initially and pos 1 was
going in reverse at 30 percent mains, at full tilt as though on 5. At 50
percent mains for half a second, no motion, nasty buzz and mains draw of
over 1 amp. Where to go from here , I assume pos 1 is not reverse or it
would be marked R, what have I miswired ? Time to delve into the handle
and
its switches

Stamp an R over the 1 and call it quits.

quits being a puff of smoke, disable the "1" linw when you know which it is
, maybe.
Getting inside the handle it all became obvious once you know which is the
low current, low speed lead when they are all the same size multistrand
gauge of wire going into the handle . Inside just a simple 1 to 6 pole sw
and 2x 2 position slide sw, then 2 off x2 yellow blocks, 2 blue disc ceramic
over the commutator and no electronics at all.
