Interesting piece, Brian.
When you can, or feel like, post us a picture of the whole weapon, to enable us observing this example relative proportions; there are some sections missing.
I wouldn't know why it ought to be German, although i ignore where it is from.
Interesting thing being a left hander, it is always an added value, in collecting terms.
But you know, sometimes a left hand example is not like that for having been so commissiioned, but because this was the general manner to make them ... like in Sri Lanka, for instance.
This not being the case, i would say
.
