Interesting engravings

[Big Jim]

Can anyone help me with the gun? Maybe someone knows it or has seen it before. I bought it at an auction a few weeks ago. The previous owner couldn't tell me much about it, only that the person who owned the gun before bought it at a museum auction. I find the engravings on the barrel very interesting. I tried different exposures when taking photos, but I couldn't get the photos to turn out well enough to show what the engravings look like in real life. You can see it a lot better than in the photos. In another post I asked if anyone knew the name of the gunsmith on the barrel. I would be very grateful for any information.
