Sorry. Meant 53.

There was still a screw/fastener industry in Rockford when we lived there, but United Technologies bought it out, and they were notorious for off-shoring. I worked for a time at Eclipse Combustion, that made the industrial burners that were placed everywhere from the GM paint room to the Moon Pie factory.
Even TAN Books was housed in a 1930s era plant on Harrison Ave. that built tank parts during WWII.
