If we assume that the flywheel is on the engine side of the box then the gear change is on the left side of the vehicle so I would assume it's not British.

I would say it's likely to be from a tractor. _________________ 1989 2CV

Did they make the Riley Ditchfinder in LHD configuration?
OR was there a Continental or American car using the gear shift next to the door system?
If the lenght of the gear shift remote tunnel is not sufficient for that idea, what about a single seater with the driver sat virtually over the rea of the gearbox and the shift falling to hand on the left. _________________ Bristols should always come in pairs.

I would say it's very old; The casting is broken but not terminally so. The difficulty, as has been mentioned, is the LHD configuration. Even early European cars were RHD and I can't think of an American with that type of gear change.
A difficult thing to date let alone identify. |

Now I might be wrong but I have seen one old vehicle with a flywheel type thing at the rear of the gearbox as a brake like a transmission brake on a Land Rover, but its all guess work until we can find more info _________________ It will come in handy even if you never use it. |

This is surely just a separate right-hand drive, three-speed (?) and reverse, right-hand gate-change gearbox?
That “flywheel” is too small and would be on the end of the engine’s crankshaft/clutch assembly connected by a flexible composite disc to that three-fingered spider on the left-hand, front-end of this box – and it wouldn’t have bolts sticking out, which look like part of a drive-shaft coupling. It is more likely the drum of a transmission brake. That style brake could indicate it’s earlier but some Humbers from 1910 until at least 1927 had a separate gearbox with a fibre engine to gearbox coupling, a rear contractile transmission drum brake and a large diameter fibre coupling onto the Cardan shaft. Some separate Rovers boxes were a bit similar with a transmission brake until quite late. There were probably more likewise. DG. |

Cargy. I think you are right. What we have been calling a flywheel is in fact a transmission brake - common on many Edwardian/ vintage cars - and that makes it a RHD British car.
I may have mentioned the Adversane Scrap yard before... but I recall back in the 1970s seeing a shipping container stuffed full of these type of gearboxes (and crankcases).
The value was in the aluminium. |
