Bellows thermostat for tr3 and Metropolitan Nash Thermostat are interchangeable. There is a guy selling some NOS ones for the metro for 22.00 out of Kentucky on eBay. I think were made right there also probably back in the 60ites. I am not sure if he knows they are interchangeable with the English stuff. I bought one and they look ok, so I thought I would tell the forum. If I remember correct, the tr3 and metro rag top are the same also.

SP,

I took a look at the auction, and while it is a bellows thermostsat, there is no ring to seal off the bypass. What operational difference that makes is debatable, but it may matter to some.

Indeed the sleeve to block the bypass would be the only reason for using a bellows thermostat at all, IMO. A modern "wax pellet" type works far better at controlling engine temperature.

Hmmm, I have a Lucas LF2 bellows-style thermostat, and besides the TR 2, 3, 3A and 4, others are specified: Aston Martin DB5, Jag 120 and 140, various English Fords, Rileys, Wolseleys and a Rover.
No Metropolitan mentioned. Were Nash Metros only sold in the States?

According to Wikipedia, they were sometimes also sold as Austin Metros in the UK.

Well done, Randall! Should have read a little further:
Austin A35, A40, A50, A55 Mk I, A90, A95, A105 and.....Metropolitan!

Although, in my defense, I was looking for Nash.

Great catch!

Ya I am not totally sold on them either, I just like the box and complexity of the thermostat. I did drop it in hot water, and when it opens it kinda makes a flat area for the shutting off of the hole, but again I have the real deal blanking one in my driver.

Just an FYI... there was also a Hudson Metropolitan. Mostly badging and some extra chrome. Fairly rare, I only know of this because there is one 'parked' locally that I have seen.

At that point, Nash and Hudson had merged to form AMC, so it was just a matter of putting a Hudson badge (and a few other trim items) on the car, and selling through Hudson dealers. Later on, AMC dropped the Hudson and Nash names entirely, calling the car simply "Metropolitan" and selling them through Rambler dealers.

[Would you happen to have a seller ID or auction number (link) to these?] The bellows-type thermostat are also useful / mandatory on some Heralds due to location of the temp. gauge sender on the earlier Heralds.

Can you expand a bit on that, Andy? I don't understand. The bellows thermostats are larger in every direction than a wax capsule type, so it can't be that the sender interferes mechanically with the thermostat. Can it?
