I personally think these tend to be able to work for either genre', but if you're asking on VSF list...

While Victorian engineering tended to depend on the (sort of) new magic material, iron, there were still plenty of occasions to depend on wood. I point out that the western ACW navies were dominated by timberclads.
Heck, what is being argued on TMP as the finest all purpose fighter plane of WWII, the Mosquito, was mostly wood.
Looking forward to detailed developments!
Could I have your puritanical twin's eMail addie, by the way?
