Early 19th Century Briquet Identification

[Richard D Wales]

Good afternoon all,
I hope someone will be able to help identify this short sword/briquette.
The blade is 643mm long, 35mm wide at the ricasso and has a broad, shallow fuller on both sides, beginning approximately 120mm from the ricasso and terminating 100mm from the tip. The spine is a shade under 7mm thick at the ricasso.
The brass hilt has 36 ridges and an acorn quillon. There are maker's marks but they have been almost polished out. The one on the acorn quillon looks like a C in an oval and the one that I can read on the front of the crosspiece looks like a G in an rectangle.
Initially I thought it might be a French AN IX naval briquette but the scabbard has me stumped. The very long frog stud looks Prussian to me but I haven't been able to find anything exactly like it.
The frog stud has a polished out stamp on it but it is illegible. The foot of the scabbard is also marked in a couple of places and has a date of 1823.
Is it possible that the scabbard and briquette are a later pairing?
Any suggestions will be greatly appreciated.

Here's a pic of the date and a stamp on the foot of the scabbard

I would be very grateful if anyone has any input as to the country and model/pattern of this briquette.
Thanks

All I can say is the briquet itself could be a variation of a French AN IX, but the scabbard does not fit that model. I couldn't find any stamps that match your description for that era. Many countries made briquets in many variations, so it's hard to say where it could be from.

Thanks for your input Max. I appreciate your help.
