Speaking of OT, and "19th C. skills"...
See my post in the same thread. The series by S.M. Stirling I refer to at the end suggests that some folks who've cultivated skills from earlier centuries than the 19th, as a hobby, may come in handy, too.
(On the other hand, it may all be propaganda to convince us that the SCA is actually worth something beyond an overblown costume party.)
