Just what I wondered, and happily have managed to patiently rebuild another old 11-toothed stater motor among my spares - and it works!
(ps - aye, the sight and sound of the pipes and drums at our annual Lonach Games in Aberdeenshire is a magical experience.)

Does a Lucas Bendix 10-tooth starter motor fit a petrol Lightweight, or does it have to be 11-tooth version?

Thanks for that, Dormy. Think I'll give it a try - and make sure I always have the old lightweight out of gear first!
On internet sounds like the starter solenoids in old British cars often had a similar version with a push button, and apparently Land Rovers?

Acquired a push button starter solenoid BCA4501 in spare parts buy.
Says online useful for working solo on the engine and seem to remember my father had car with one years ago
Has anyone fitted one of these? Wondering about the wiring.

Remember seeing online item about the Lightweight Hella flasher unit, which pointed out that many can be repaired after carefully loosening the tabs to get to the inside?

Still running the old 2A but can't find the pics I took back then. Hate to admit it, but since replaced the thin basic seats with the comfortable seats from my former Austin Champ! Heresy, I know. But reliving my youth had its limits, particularly on Aberdeenshire potholed roads! However, try the li...

Re the link there - the cushions/squabs on my '68 Lightweight are original very basic versions and thin. No angle to the base and no ply base board.

My headlights have stopped working altogether - no high, low beam or flash - although sidelights, indicators, horn etc are all ok.
Anyone tackled similar problem?

I sent off registration from the military vin plates and received the history of my ex-Army 2A from the Royal Logistics Corps depot, and later RAF Lightweight from the RAF Museum Hendon. Contact details are online.

The old two-pin spotlight plug fitted into the red/black socket on the vehicle dashbioard.
