This from Dan Jasina:

I toured the American LaFrance museum in North Charleston, SC on February 5, 2014. The first Chicago FD snorkel, a 1958 GMC/Pitman Mfg. was display. The apparatus was restored by Snorkel in 1988. This museum has the largest collection of fully restored American LaFrance apparatus in the country, hands-on interactive safety exhibits, and a children’s activity center.
