I know its slightly out of our period, but...
I was reading something from about 1718, describing Tibetan soldiers.
In the original Italian the word used was 'spingarde', but it was translated as musket.
I thought they were quite different, and that spingarde would have been almost archaic by the 18th century and so very likely means spingarde rather than musket.
Any thoughts?
https://it.wikipedia.org/wiki/Spingarda suggests that "spingarde" originally meant springald, but came to be used for firearms from at least Leonardo da Vinci's day. Might mean something like a wall-gun or a jezail rather than a musket, perhaps?
Something like this, perhaps? I remember seeing something similar in 19th century photos of Tibetans, though the guns then were matchlocks, IIRC.
