Need help identifying this flintlock

[CalS]

Hello and thanks in advance for any help. This was a hand-me-down and all I can find is G R Douglas 45 cal on the barrel. It appears to be silver inlay. The stock box was hand chiseled out. Gun barrel is 42" and 561/2" overall. I wish I knew the maker or even age. I would appreciate any help. Thanks, Cal

GR Douglas is a well known barrel maker located at Cross Lanes WV.
This beautiful rifle is a contemporary custom build I think. I wish it were mine!
