It is a Beseler 57MB. Very fine specimen. Thank you so very much, Pete. We will have to meet somewhere and shoot.
Wow! This is a huge honkin' enlarger for the huge honkin negs my huge honkin camera makes. This thing is the size of my chair at home. I can't wait to play.
Nice new enlarger!
I have had good results using a yellow filter in addition to the multigrade filters with an older cold light head.
You will probably need a 210mm lens, they show up on e-bay frequently.
