My Archivist daughter just sent this ULF camera notice to me:

The Nebraska Department of Roads Photo Lab is scrapping their Robertson 41" Tri-Color Horizontal Copy Camera (see specs below). They are no longer using it for anything significant and need the space it occupies for other purposes. I will be sorry to see it go because we have used it to reproduce many of our oversized drawings. I am not sure what we will do now to copy our really big stuff.... Anyway... I am posting this in the hopes that someone might be interested in it, or at least may be interested in some of the parts. Realize that this is a huge camera, and it will cost quite a bit to remove it from its present location.

Serious inquiries should be directed to Jay Bailey at 402-479-4306 or at jbailey@dor.state.ne.us by February 4, 2005.

Please feel free to forward this to any interested parties.

Wow...wish I was nearby...would be worth it to haul it all away just to get the 24" lens and the vacuum frame. And the 30" lens. And at least the front section of bellows. And...and...and...I guess it's a good thing I'm so far away!

Yeah...that was pretty much my reaction too. I just flew over Nebraska on my way From Southern Cal to Philadelphia. It looked really, really white and cold down there...
