My brother in law got this in a box of bits that came with a Vincent Comet and we're a bit stumped.

The Comet got put away when the owner was too old to ride it any more, in the late 60's.

I haven't got a clue but over 2 hours and no-one has come up with an answer is some kind of record. surely.

Smith's make guages so my guess is it's a sensor for a guage. The bottom bolts look like power connections and the pipe in is probably what it is sensing, oil pressure? Temperature of something? No idea, and the padlock looking hook on top is really throwing me!

ETA I looked up a comet and they only have 2 guages, anmeter and a speedo so could be an anmeter of some design?

The electrical connectors looks a bit beefy. Could it be a heater of some kind?

Or an old design of ignition coil? And the hook on top rotates?

Is that a tube in the middle on the left - between the electrical connections? And the knob, bottom right, looks like it might be an electrical pump or primer?

No idea but maybe some form of fuel pump or similar? Something

But as above Smiths made gauges

Is it some sort of fuel shutoff valve?

Smith's (although mostly known for clocks, tachometer etc) did branch out into other stuff too.

I suspect this would be a part of one of their early starter systems. Looks solenoidy to me...

Can't find anything similar on teh Google though.

srob in the Bike section is your best bet.

Well here's the thing. The owner used to work at Handley Page and the bike has period aero electical connectors on it, and other non bike related bits/upgrades - the best period bits to do the job, basically.

So it could be automotive, or bike, or aero... We have no idea!

The box of spares are all sorts - some things you'd never want or need on a bike, some bits (like the original brake hubs as the owner had upgraded to Black Prince brakes) are obvious, and there is this bit...

I thought I'd throw the pic in here (but with the cover story) rather than the Bike section to give the rest of you nerds the best chance!

And as others have said, Google Lens shows nothing like it.

So maybe drop it into Bike for Srob, and Planes for Eric?

It’s a brimbleshaft from a 1936 Stephens-Whippet 250.

yes

Some sort of priming/pressurising plunger with a pull-up handle to complete the starter circuit?

Can you strip it down? Are there any screws on the reverse?

Is there just the single fluid port?

Might it be a vacuum operated windscreen wiper motor? The studs and nuts for mounting the motor, the pipe for vacuum connection and the rotating 'padlock' rod the spindle to which you mount the wiper arm, with the 'hook' bit allowing you to operate it from inside the windscreen as required.

Ooh that's a good one! Or even a speedo operated one... I think early 2cv had them?
