Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Looks pretty darn close to me. I reckon it's maybe like the eachine and other engines are to the M90? Those look the same design also. All CNC stuff.

The seller, Enginediy states that they have been doing “retail” since 2009.
They are located in Shenzhen, Guangdong, China mainland region. I noticed that they offer copies, of copies, of copies of many items. They also drop-ship and drop-ship and drop-ships so much that the exact photos of many of their offerings are super abundant on ebay and amazon under numerous sellers i.d.s’
Some of the scientific school models are copies of models that used to be made in Japan, Taiwan,  and Malaysia . Those were often offered for education sales by Cenco about 10 years ago plus.
Enginediy sure does have a picturesque Chinese cornucopia of engines and objects that copy/quote “offer the right product with low price and ....” .  Hummmmmmmmmm.....they are an interesting outfit .. perhaps a portal of a portal with affiliates of affiliates ..

See link below, I am not spending a penny on any Chinese product to be used against the US & its allies. They exported the pandemic intentionally and we are suffering while they are prospering from our setback; sorry.

Bonjour,
This is Jin's machine just with an engraving on the fuel tank. Please note that the video engine has not this engraving
My concern is that I paid Jin's M12 about 100 $ more than this one
