    Great find

    and the only names we recognize today are Dunham and Crane.

    The Marck trap is interesting, with its Bourdon-tube innards. A company called Haines made similar traps at least thru the 1940s.

    We should pass this along to "urban explorers" who like to go into abandoned buildings, to see if they run across any of these things.
