Clock “guts”?

[brianc053]

Hi everyone. I found this metal detecting today and I’m wondering if any of you are experts in clock parts. I can’t find any words/numbers/markings, and I’m not sure where to start my research. (Normally I’m happy to do a lot of google searching, but in this case....I’m lost).
Can someone help me with some ideas please?
Thanks!

Either a clock or a water timer for sprinklers.

Try soaking it in apple cider vinegar for a bit and you might find some markings on it. Probably the guts of an old alarm clock from the 40's or 50's is my guess.

Can you provide something for scale in your original photos?

Sorry I should have done that! I put a dime in the picture.
