Hello everyone,

I was wondering if anyone could tell me if this is a real Thermal Hopper? or any information.

Thanks in advance.

Head looks correct as does backplate, externally the cylinder looks correct. Should be dual bypass, tapered grind with SPI.

Front end /crankcase is typical of most early cox engines. The front acorn nut has been ground down or damaged.

Thanks Cribbs, it looked legit to me as well but wasn't to sure about the ridges on the side of the crankcase next to the backplate. I did purchase it so have to wait to inspect it more.

Thanks Canso07.

I think what you are seeing is just a casting flaw.

Hello everyone,

my name is Nicu, I am from Romania and I am glad to be part of this forum.
I have a limited collection of cox engines at the moment, but I want to expand it. At the moment I am looking for a Thermal Hopper, if anyone has one for sale, I would be happy to discuss a sale price.

I look forward to relying on your support

thanks for the answer, the first option is much too expensive for me, I would like to fit in a maximum of $ 90.
I will follow the auction course on ebay.

thanks
