I'm prepping it for the paint now, so have all the chromy bits off. 
It's fairly rust-free, since it was in a garage for over 20 years. I 
have a disc-braked wire-wheel rolling frame in a field near here and 
plan to swap the rear axle and front suspension between the two.

Many thanks for this! I use a Facet pump on the Cooper S, along with a 
pressure-regulator. I have the original Lucas pump on the A, but of 
course it's not working. I'm used to fixing them, but suspect this one 
will have a duff diaphragm, so will probably use the same setup as the 
Cooper.
