I have one like that.
If I recall correctly, I paid $20 for an old holster and it came with a pistol. 
I've shot it with VERY modest loads. They are good fun. Been meaning to try some BP but haven't gotten to that yet.
Edited to add: Oh yeah, the Owl's Head looking 'down the barrel' indicated from pre-1897. FWIW
