Hi Mark,
No chance you show us pictures of your pike?
I wouldn't know about Spanish colonial versions (or any other
), but i can see that 'homeland' versions had langets, if you mean by langets the side straps that fix the socket to the haft.
Here you have the Spanish boarding pike (chuzo) model from circa 1820, with description and measurements of blade but no mention to the haft, and a later model (1870's), followed by two other variations residing at the Naval museum of Madrid, being one with two heads. Haft lengths on the classic versions are 1,76 mt. and 1,96 mt. The double headed one is exceptionaly short, with 1 metre. no mention to what type of wood was used in any of them.
I hope this is usefull ... at all
Fernando
