I think Eshland might have been formed in 1979. After Eshland closed an employee of Eshland, Jeff, opened AHS and brough with him some of the Eshland designs. I think AHS started up sometime in the 90s.
My understanding of the history of boilers of the coal gun design is that the basic design originated with research done by Penn State and was first sold commercially by AA. A modified AA design was sold by Eshland. A modified Eshland design is now sold by AHS. Perhaps Patrick can correct this history if it is incorrect and fill in some additional details.
Bob I was basing the year 1979 for AHS off of the prototype they built in 1979 which is still running 25 or so miles from the factory I believe that is what Patrick said could be wrong on the miles
