[alt-photo] Re: a large-format horizontal enlarger with tilt shift mechanism?

[Greg Schmitz]

Hi Ryuji,

Long time no see.  Durst and DeVere horizontal track enlargers (810) 
were available for cheap (or for free) a couple of years back.  I was 
offered one if I was willing to cart it away - you might also be able to 
modify a process camera too.

Just think'n.

Good luck with your project.  --greg
