Unusual powder tester for comments

[fernando]

Well, unusual for me, as i have always seen these things shaped like pistols ... handle, trigger and all.
This one has a more austere look, more like a 'lab tool' .
... and the ignition system is fascinating; different from the classic flint or percussion mode. Was the technique priming the touch hole lip with some powder or instead the match cord way ?
An 18th century example for sure, right ?
The handle is horn; which type, i don't know for sure.
... as i wouldn't know the origin of this device .
Any help in part or the whole query, please ?
