Pinfire revolver no serial number

I suspect Belgian. There should be some kind of proofs on the cylinder. If you can find "elg" in a circle or shield that will confirm it was at least Belgian proofed. S/N's were not commonly used at that time. Most likely the only numbers you will find will be assembly numbers. I'm not familiar enough with the revolver to know if it had a model number or name. Model #'s were not in general use at that time either.

The thing that caught my eye is the grips. I believe they're horn? Beautiful.

 

The gun was badly rusted and then reblued.
It's only value is as a curio or keepsake.

 

Like "sharps" is saying: probably belgium
The bridge with 2 screws over the cylinder , between the breech and the barrel, is a patent by Janssen.
