Great History Lesson Jet!
Sounds like you've your homework. Yes, they do their own castings still to this day in Fairfield, and a very dirty and OLD casting plant to boot! Did you contact folks from Fairfield for the info on Dexter, or was their an outside source? I never realized how much is still done down there. I had no idea that the design principles of the Dexter commercial machines is based on Bendix tech - simply amazing. I'm sure next time I'm down there, I can find some info at the Library in town if needed.
Us 'townies' didn't pay much attention to Dexter unless you were employed there - and waved at the strikers while they cheered on the side of the road! I left Fairfield almost 3 years ago now... And no, I didn't participate in what was brewing on the North side of the tracks, if you know what I mean =)
