Pre-war JEP abandoned model train - Rusty locomotive - Restoration

Here is a new video !! It’s been a while ! Sorry about that... Many people asked me for a longer video with more details ;) This is a streamline model train produced by JEP for Unis France before 1940, probably between 1932-1939, but not sure... If any of you have more infos... It’s a 120 type / 0 gauge. There was an electro system in the tender, I guess the original model had a full electric motor. Each part was completely seized and pretty much rusted. I thought the spring was broken then I was very surprised that it wasn’t. What you don’t see in the video is that the spring finally broke during an electrolytic bath 🤔 I had to lift one end of it so the motor is a little less powerful.... It’s not obvious on the video but I spent a couple days trying to bring this pre-war clockwork back to life ! Please watch till the end to see this antique rusty locomotive in action ! I’m aware that dark brown chocolate is not the perfect origina
