G'day Nick,
Seeing that there is no brake plate anchor, the handle bar clamp and those headlight stay mounts I'd say light weight. looking at Leon's page. 1932 B32, L32. 1933 B33. 1934 X34, B34 up to 250cc.

I'd say that the brake rod lug and the simple star washer damper narrows it down to 1932 B32, L32-2 or L32-3. Ron

They are B or L model 250-350
32 saw the introduction of the ears for the headlight
However your top yoke was last used in 31

They do have an anchor point for the brake it is on the timing side just above the axle.

Definitely not used on B2 Or X0
The anchor point is higher on these models
Also they don’t use a solid brake rod, they used a cable that enters from the rear of the fork.

Yep the picture I posted is a 1932 B1 (not B2) Ron
