ever heard of steel frame house co., circa 1930's ??
i am currently doing some modification work on an old 4 story apartment building in penna. supposedly built in the 30's. only in the basement is the steel structure visible--wf beams, open-web joists, some small i-beam joists. the elevated slabs are concrete poured on a draped steel mesh--in lieu of decking. the little i-beam joists have sheetmetal tags attached to them saying, "steel frame house company, pittsburg, pa." and a contract number and piece number.
if anyone has any experience with this stuctural system, i would appreciate hearing from you.
i had success researching old drawings with the state architectural historical society. they may have copies or originals of the building drawings and contracts. the local government permiting body may have references. also check
there is a great new show on pbs called history detectives.  they would probably love to tackle this.  a recent show was about trying to determine if a house an older couple lived in was one of sears and roebucks mail order houses.  in the early 1900's you could buy a complete house with all the pieces marked for assembly from a sears catalog.  i think they had 150 different designs.  this one was difficult because it was in firestone park, a company town built for the first firestone tire plant.  after finding much contradictory information they determined that the firestone park houses were a one time only design not available to the public.  i hope you will contact them because i would love to see this one on their tv show.  they can be contacted at the address below.  they do a lot of legwork and may come up with the original drawings for you.
