Pre 65' Trials bikes and other longstroke singles?

Hi everyone hope we are all well two posts in one this

firstly just wondering if any of us has done pre 65' Trials.

I'm considering stuff to do an look at after the House move to Scotland in January.

I've been thinking of things I fancy having a go at top of the list is Pre 65 Trials riding, I didn't really enjoy the green laning on the crf 300 rally, but think a closed course could be cool to improve my skills.

An was wondering if anyone had any advice on bikes or general bits of wisdom?

The second thing I was thinking about was long stroke road based singles.

At the moment with my nerve injury British twins are a no go for kickstarting where as my 1927 Norton 16h has been a peach for that. I've nearly finished the WD16h to use daily.

An tbh I've had so much fun on the flat tanker it's had me thinking about a totally different approach to my motorcycling which has been spurred on by the nerve injury.

I'm also thinking of bikes other than Nortons to widen my experiences a bit.

Ideally looking at stuff with good spares availability as whatever I get I'm gonna use regularly I've got a few ideas kicking around in my mind but thought I'd see what the general concensus was

Thanks in advance.
