Can anyone shed some light on what I have here?

My first thought is Khyber Pass.

All I can tell from that partial pic is it's a pinfire of unknown origin.

You more pics to get a better answer.

A few more pics of the entire gun, both sides and any markings.

Just posted more pics. Thanks for your feedback!

Nifty, but no clue here. Markings would indicate Khyber Pass to me as well. BUT, I am as far from an expert in odd and unusual pistols as you will find. Very cool, make a really neat wallhanger in a shadowbox.

From the ELG mark on the cylinder it was made in Belgium. It is a pinfire but it's missing the ejector assembly.

Its a Belgium, probably 7 mm, pinfire revolver made before 1893 ( the ELG proofmark in an ovale was in use before that date )
You probably have a lettre with a crown or star above on the cilinder .... crown = before 1 january 1877 , a star = after january 1877.
The screw and ejector rod are missing

Here is what one looks like with an intact ejector rod-

If you are not familiar with pinfires, each cartridge has its own firing pin. Very early ignition system, now considered obsolete.
