Ran across a unique bit of knowledge. At least new to me. While taking a tour of the US Navel Academy in Annapolis MD I entered a building of boat models dating back to the early years of the navy. The tour guide stated that the construction crews did not work with prints or written plans but rather worked off an exact 1/4" scale model for all features. Humm...Neat!!! Dozens of perfect 0 scale models all over the place.
If you ever want to drool over some super 1/4" scale model boats this is the place to go. OK, not for sale and only useable for historic docking such as at the Baltimore Inner Harbor, Penn's Landing and other such water front displays but eye candy none the less.
A variation on the reverse engineering certain manufactures use when copying somebody else's models.
