i would say look for a post war model. No mag. It quite straightforward to convert the Dowty forks to conventional springs thus eliminating the leaking air threat. Fixed lugs on the frame for the gearbox, a more stable frame set up. superior front brake, the myths about setting up this brake are just that, in my opinion. The radiator has a car type core as opposed to the pre war honeycomb which may be easier to repair / replace if necessary. Yes the post war bikes are heavier but in my practical experience of them both, it makes a better bike for regular use. Of course, this is just my opinion. good luck. 🙂
