There are no markings on the movement I can see.
The back of the case is marked

The movement was badly bent when I got it, including the faceplate supports.
I have managed to get it fairly straight now & working, but I am certainly no clockmaker.
You can see the plate to the left of the mainspring barrel is stil slightly wowed, but it was 1/4" more out when I got it. Must have taken some knock as even all of the faceplate supports were buckled. Still, once straightened out as much as I have done, with some tweaking here & there, it is working again. Util I put it in the case, now it doesn't want to run. I guess something is squeezing it somewhere on the side.
I'll have to play with it some more when I get a chance.

For now, I am leaning towards Ansonia as the maker????

Maybe its a Timex (takes a lickin & keeps on tickin!)

If it were mine I'd take it apart and clean it. Its filthy and that could be the biggest problem.
Good luck.

Yes, it is filthy. However, I am not a clockmaker, if I take it apart, I assure you, it won't work again. I just actually got it ticking away just now in the case. It now is running fine & keeping great time despite needing a bath! I wish I had thought to take some pictures of it before I straightened it out!
