my dad has one of your TM Dave, the one from John Flynn, its still going strong its had a make over and new fresh water tank, stainless steel, it has 1000 psi pump and roots blower and kerosene heater, (gives you steam if you want it) its as good as many real TM s out there !!! and is cheaper to run as its electric so no worry about engines going wrong, and no fuel bill.
PS. its still earning good money every day!! ill post a pic of it later on.
