Marion apparently built some machines for the Frisco ages before I got there - maybe 6 units? - had to be steam ditchers or wreckers, but I was unable to find their print books. They were probably stored in one of the pattern storage buildings - a nightmare to find anything in there - climbing around in the dark with the bats. The records storage "system" for the ancient machines were print books wrapped up in dry linen bags - with a wired on tag that indicated the shop order number and serial number of the unit. There were gearing sets for south pacific sugar mills - and WWI shore defense guns (rail mounted) - and who knows what else was in there. Everything up to about 1950 was mostly destroyed when the building was "re-purposed". They should have given all of that stuff to the Smithsonian - or sold it as antiquities - instead it went in ten wheel dump trucks to the Marion County landfill.
