Any ideas what it was used for? Flylo?

Does the large end with the cap on it, ratchet or turn?

Whatever it is, if you're carrying it around watch out for drones. I think it may be Evull.

No worries.... they don't attack their own!

Attachment end for a chrome spun weezy cable, that particular one has an isolated rubber mounting to accept a canuetin deriverator, now if that happened to be bolted to the CSWC you would have something that would be worth far more than a paper weight or door stop, but as is - that's all you got.

take more details pics and describe what rotates and stuff when you get tired of all the smart arss answers ;-)

I want one! Did they have any more?

At first glance, the finish of the main body looks medical. But looking at the painted pieces, I'd say aircraft. Beyond that, I'm not much help. But then it looks like no one else is either. :p

My guess: it's a cartridge engine starter or powder operated rotary actuator, like a small version of a Coffman or Breeze starter. Does the lever on the right allow the end to open, like a gun breech?

Yup---------Device is beautifully machined/finished, probably by an arms manufacturer???????? Breech is to the right operated by the shiny lever. Pretty simple but I could not see inside far enough to observe a piston which would operate a rack/pinion attachment to the hex nut? Pretty slick anyways.

James Stewart in Flight of the Phoenix, 1965, used one of these to start a radial. I doubt it was the 28 cylinder monster found on his C 119 Flying Boxcar.

GThese days, that might still save you in the event of an unscheduled landing.
I imagine if you packed it in your carry-on, you could miss the flight.

That's crazy - never knew they even built such a thing, very interesting and im sure worth some bucks to the right person...

The hex nut may be a cap on a pressure fitting, often the breech was just used to produce gas pressure and was connected to the actual work performing element by a flexible line. The cartridge starters worked that way. There are a number of other applications for these types of things, like ordnance ejectors and such.

Good going O.C. - it's no Victorian Picture Nail but gotta give credit where credit is due :p

I think it's a separator, for separating Guido from his money. :D

Searching on the term "Cartridge Starter" brings several results,
including the ubiquitous Wikipedia entry. Pictures however are
not so common as words.

A check on YouTube brought up a few entrys, even a 4 minute
segment from the film, Flight of the Phoenix, that has already
been mentioned. One clip of a first fire for a restoration project
shows the cartridges and a brief shot of the starting mechanism
- different than Guido's, but instructive all the same.

I would accept that is a cartridge starter from what I can see of it.

Right now we are working on a Percival Provost** which has an Alvis Leonidies engine with compressed air and cartridge starters, the cartridge starter has a five shot magazine and does indeed have an appearance somewhat like Guido's find.

**Partially preserved primer painted petrol piston propeller propelled Percival Provost.

It's a part of Sir Johns lower limp er limb. Which without this device , is also quite limp. Alistair

Optics, Artful, others familiar with cartridge starters.

How is the short, rapid, high powered release from the cartridge
converted into an extended duration of rotary crank motion?

Does the expanding gas charge a spring-loaded accumulator, pushing
a piston back against a spring, storing energy in the spring which
then releases, driving the crank through several rotations?

It is all to do with the burn rate of the powder...the gas drives a turbine that is geared down by a couple of worm and wheel stages.

Not a clue. Perhaps more pictures, from different angles, would help.
