Headlamp rim clamps

[Peter Lloyd]

Could a member please provide photos of the type of rim clamping method for the TA for the original headlamps. Enough to clearly show what is at the base of the rim and how the clamp screw engages. fit. I assume the rim clip has a slotted hole to allow the screw to hinge down without needing to be completely withdrawn. Any help appreciated. Mine is a '37 but I believe this method carried over to the TB and maybe the TC until changing to the spring clip clamp.
