The motor start capacitor needs replacing but it has no visible markings
on it due to several paint coatings !

With capacitor removed the motor will run with a hand start and I can
hear what I assume is a centrifugal switch clicking on spin up and spin
down.

Any advice on what size capacitor to buy and try ?

I have one of these motors and it does not appear to have a capacitor on it . It starts but dips the lights in my workshop as it is pulling a few amps on
start up is the capacitor internally mounted?

value is not generally critical. IIRC something in the 10-50uF 400V
rating or 600V if you can get it.

for 1/4bhp you might get away with even less.

Dozens on ebay.
