I got that tap and die set from a friend of 25 years who is now moving to a retirement apartment (assisted living facility). He was cleaning out his basement workshop and offered me this set that belonged to his dad, who worked as a machinist at the Norfolk Naval Shipyard. His dad passed away a couple years ago at age 96. Bob is 74. It's hard to tell scale in the picture, but the wooden box is over 2 feet long and about a foot wide.
While it didn't build the Ark, you are not far off, I'm sure it was used in the construction of a bunch of Naval vessels...
