Re: Trying to identify
It appears to have a hooked breach. To remove the barrel, push out the key that pins the barrel from the forestock, remove the ramrod and carefully tip up the barrel. The patch box is of the type commonly found on flintlocks, so this gun may date back to as early as 1840. This gun has very nice/graceful lines and has a beautiful patina--it has been well cared for. I wouldn't do anything other than wipe it off and use an oily rag on the metal parts. It's a shame the horse is missing parts of its legs, but it is still a very nice piece. A picture of the barrel end and a measurement of the barrel width would help determine calibre. Is there a front sight? The lock can be fixed--carefully remove it and send pictures to DixieGunworks.com. They can send you the proper spring.
