   If by 'head' you mean a lamphouse Arista makes a 
coldlight head that fits the Saltzman. There were a number 
of heads available for it from both the original 
manufacturer and also aftermarket. The original lamp on most 
Saltzman's used mercury arc tubes but there was also a 
focusing condenser head using a large incandescent lamp and 
a fluorescent lamp head. Color heads were available as 
aftermarket items. Saltzman made three 8x10 models, a studio 
enlarger, with a single sup****t rail for the bellows, the 
deluxe studio model which has two sup****t rails, and the 
10x10 aerial film printer, similar to the deluxe but even 
heavier. These were the best LF enlargers available at the 
time and maybe ever. When setup right they are very smooth 
and stable.
   Originally, they came with a shutter similar to a Packard 
shutter, which fitted under the lens. This is because the 
mercury arc type lamp must be left running continuously. 
Actually, this is a good idea for any gaseous discharge lamp 
like conventional fluorescent lamps. I have a Saltzman 
catalogue but its among my famous stored away stuff and I 
don't know where it is any more. I've never seen on on-line 
anywere but they may exist.
    For those who have never seen a Saltzman enlarger they 
resemble a vertical milling machine.
