Clark,
Ask someone who is used to doing shrunken heads,...they should know! :-)
Re these coconut flasks;
They always seem labelled powder flasks, but as the nozzle is so large, I wonder if a rum flask or whatever may be the real purpose.
Tim,
I don't know much about the wee gourd-shaped horn I showed above. I know it's English and was well made.
In another thread I could post pictures of it if you like. The base unscrews for filling, and top unscrews as the measure.
18th VC for sure, but didn't realize it may be so early.
