G'day, I recently picked up these girders though I'm not sure what they're from, if anyone has any idea please let me know, I can supply some measurements if that'd help.
At first I thought they were Triumph. But I'm fairly sure Ray is correct with Ariel. The give away is the brake rod lug on the front right down tube, and the side check spring and mudguard lugs.... Ariel and Triumph stuff can be very similar. Something to do with Val Page and Edward Turner I think. Ron
They are Ariel, but the pre 1939 type. In 1939 the outrigger springs were fitted,so the lower headlamp mounts were moved from above the side dampers to the main tubes. The top yoke is for the deluxe rubber mounted bars clamp.
Cheers, Mick.
