Hi,
I've had this headlight for some time and would be grateful if anyone could shed any light on which bike its from (came with a load of BSA stuff but that doesn't mean much I know.... confused).

Its got a 7" Lucas glass but the lighting switch and ameter are off centre by quite a bit? Could these be modifications (added later?) - surely it wouldn't have been made like this would it?? Pics below:

Cheers

Hmmmm? well the straight part of the brackets suggest girder forks but as for the loops on the end I'm afraid I don't know. Have a look inside for any signs of green paint in which case if so, would suggest a WD M20.

The bikes that I have owned with an ammeter & switch have these items mounted in a small panel and this panel then mounts on the headlamp.
Looks like a bush mechanic bodge ....

there should be a model number underneath if its lucas,just by the hook,dragonfly websight tells you which shell was fitted to which model.

I think that you will find that because it has the side struts that it,s from a BSA Gold Star.

Not any Gold Star I know about unless it's one of the very early first models. They typically have the same switch/ammeter unit mounted in the headlight shell and a curved/loop support for the bottom link running from one side to the other.
I checked out the M20 situation and the photo I found of a restoration project shows a normal switch/ammeter unit in the shell, but it did have two tubular links but for girder forks.
 I can't help with positive identification, sorry.

I'm with Flatboy.
Looks like a 60s shell with an early switch fitted.
The ammeter is a late alternator type.

Thanks for the replies guys,

Shame it doesn't appear to be off a G/Star - I'll get it cleaned up as see if any numbers appear.
But perhaps it'll look okay on a cafe racer type; one to mull over with a pint!

Cheers

the goldstar has a hole in the bottom for a pug in loom,so the headlight could be removed,does look similar on the top,check the number.

Finally got round to removing the paint to reveal its a Lucas headlight shell with the part number of 'SS700P'?
Had a brief look on Draganfly's site but couldn't locate the headlight or reference to them? Also the BSAOC site was down!

So if anyone can shed any light on what this h/light belongs to I'd be grateful.

That's the standard Lucas pre-focus shell used on loads of bikes. Given its age it's probably been bodged several times....

Thanks Ian & Wilko,
The shells looks like it has been 'improved' since both the lighting switch and ammeter are not exactly central to say the least! So I would guess from the illustrations (cheers Wilko) that it is the plain shell in the fourth vertical column, 2nd from bottom. So not a goldy and perhaps not worth much, but the glass and reflector (no pilot light) are in good condition and with a re-paint wouldn't look too out of place on a cafe racer maybe?

All members replies and input are appreciated  Grin
Cheers
