19th Century East India British Trading Company Flintlock ID?

[dtaber2]

Good morning all,

I have recently purchased this pistol but don't know very much about it. I have taken it to three different experts and have been told three different things.

The lock plate is stamped "1806" with what appears to be a British East India Trading Company Lion Logo. The barrel is engraved with a sprial pattern but has no actual identifying markers. The rest of the gun is elaborately decorated with mother of pearl and other materials. The handle butt is flat with a saddle ring on the end. I have been told by several people that military pistols from the early 19th century did not have flat butts. Is this true? I have also been told that this pistol was likely a late 19th century percussion pistol that was "re-built" with other parts. Does anybody have any information or opinions on what this pistol really is?

I've also seen informaiton regarding "Khyber Pass" pistols. Could this be one?

Any assistance is appreciated.
