Lew, The house we owned that had the Pittsburgh Toilet was built in 1952, if I remember correctly. Anyway, we bought the house from the daughters of the couple who had built the house. The father may have worked at Armco (American Rolling Mills) or Pullman Standard in Butler. Regardless, that case would have fit the first scenario you mentioned. Our daughter's home (the one that I previously mentioned had the moisture problem in the basement) was built sometime prior to 1920 and is directly across Connoquenessing Creek and Route 8 from both AK Steel formerly Armco and Pullman. That house had a basement toilet and shower, that someone later built walls around. You can tell, because it was a plasterboard and paneling job. That could have been for millworker or the first plumbing in the house. We tore out most of that because it was part of the moisture/varmint access problem.
On to the crane. Nice job with the mirror. I didn't realize until now that the scrap pile was on the back side of the track.
