Thank you so much for the hint, Teodor.
In fact, that wouldn't occur to me; i brought this thing here as a collectible piece

.
Besides, in my 'state', firearms produced before 1890 are not subject to manifest. Also the ammunition this thing would consume (.22 Flobert) is considered obsolete.
OTOH, and as you would know, in our European imagination, guns in America are free to bear all around

No deal, too bad
