Sorry, Not Sure Where This Goes - 3M Duplicating Exposure Unit "The Seventy"

For auction on eBay.  Offering an extremely difficult to find
professional exposure unit for your consideration. This is a "3M 'The
Seventy." The following is all the information I have regarding this
handsome machine: "3M 'The Seventy.' 120V A.C. 60 Cycle. Exposure Unit
650 Watts. 3M Duplicating Products Division, Minnesota Mining &
Manufacturing Company. Serial No. E70AGF930 A. Model E 70AG. Pattented
Under U.S. Patent 3234868." The bulb reads, "3M, Made By GE 120V,
54-34.  78-8454-3463-4E."  This is generally used in the medical,
scientific, or optical/photography field for imaging. The top half of
this machine plugs into the base & is turned on & off by a toggle
switch on base. The top turns on an incredibly bright light. There is
also a meter on the top w/red push button that seems to have a timer
dial, several numbers and a "darker" and "lighter" range of settings.
All red lights work perfectly. Considering the nice condition this is
in I would feel quite certain saying it is a very solid, fully working
exposure unit. Size is approximately 13" x 10" x 10 1/2" tall. Just
under 17 pounds. Excellent opportunity to purchase this professional
3M product for a small fraction of the original price.  Bidding is at
$9.99.  No Reserve.  eBay No. 2566400046.
