It looks like 501 HT, but spec. sheet has been wiped out.
It came from an auction, and has 110 volt plug. This strikes me as strange, because most hi-temp machines I have seen before are 220 volt. This one pops breaker instantly when switched on .
Is it likely that it has had a 110 plug installed by mistake
