The only natural gas AC I've seen around here was at a mall.  A
humongous Waukesha V8, probably 800-900 cubic inches, direct coupled
to a compressor.  I've heard they may decommission those.  Would
*love* to bid on that!
Hercules?  Last one of those I worked on was a HX series.  6 cylinder
flathead, maybe 900+ cubic inch?  Ran a 150kw generator for backup
power at a radio station.  Probably 1947 vintage unit.  Was replaced
by a Cat diesel 10 years ago.
