Hi, that's an unusual frame, I don't see it as a Claud, serial number is in wrong place, and if so, I would say it was closer to 1943 than 33. Lugless lightweights ( my 1921 Rudge is lugless but a bit heavier ! ) really got started here in the UK in the late thirties, with better tubing and new brazing techniques it made common sense, but it toke a bit of time to be fully excepted in club circles ( a reason for bilaminates in the forties - decorative and strengthening for lugless lightweights ). Don't under estimate Royal Enfield, the Mayfly and Bullet were two reasonable larger manufacturer machines at this time, with 531 and AP, keep digging the fork is worth a focus, I will keep an eye open.
