Beseler 23C Series III XL Condenser Photo Enlarger & Beseler Chassis

Description

For sale is: Beseler 23C Series III XL Condenser Photo Enlarger & Beseler Chassis.  Six of the nine units has the same type of camera, but two are facing one direction and four are facing another direction (they appear to be the identical camera, however.)  All are Beseler 23C Series III.
Three of the cameras seem to be missing the "variable Control Head", and they appear to be designed differently than the six of the units.   However, maybe they aren't supposed to have the variable control head?   The second to last picture shows what three of the cameras looks like. One of these three is missing the lever that you need to crank the camera up and down.  The last picture is simply all nine cameras together (sorry- brought my closeup camera and it was hard to get everything.)
All cameras come with the chassis, and eight of the nine raise and lower beautifully and one is missing the crank (mentioned above.)
They all worked the last time used according to the professor who used all of them (they upgraded to digital.)
Reasonable offers will gladly be entertained on one, or any quantity that you wish to purchase.
LOCAL PICKUP ONLY.  They are located at a storage unit in Freeland, MI near the intersection of Tittabawassee and Midland Road.  ALSO, USHIP or any shipping service can be used, but please note that I have no plans on packaging them!
My knowledge of this technology is minimum, so I may or may not be able to answer questions!  Hopefully the pictures help!
