Don and group: I agree completely. This transformer itself could be a 
work of art just in the design, paint, and attention given to details 
like the cap nuts. The insulators are a deep brown porcelain with a 
wonderful shine, like new. I've had this unit for about a decade, having 
purchased it at a hamfest for $10 from a university that was cleaning 
house. My biggest concern was using it somewhere in a rig where I'd 
never see it! It looks that good.

It didn't come with pins though, and since all the iron I've come into 
contact with either had studs or wires, I'm just at a loss for what 
these pins look like. But you can rest assured, I'm not about to do 
anything to modify this unit to simplify its use. I have enough stuff 
around here to muck with as it is. I wouldn't mind using stiff wire 
temporarily, but I'd prefer to use the correct hardware if possible.

Out in my garage there is also a HUGE power supply purchased from a 
friend mainly to obtain the large UTC (I think) HV transformer in it. 
It's close to 3 feet long and a foot high inside of a footlocker-sized 
rolling cabinet with a clear plexiglass end, and took 3 of us to roll it 
up into a pickup. It's not as 'finished' looking as the Thordarson mod 
iron, but it's not bad looking. Someday , given enough time and enough 
floor space, they'd be the makings of a great HB rig. Not sure how to 
put a viewing window in that far down the cabinet, though.
