Byers Slide Mounter 35mm and 2 1/4 pressure seals the heat seal cardboard mounts

Description

Byers Slide Mounter 35mm and 2 1/4 pressure seals the heat seal cardboard mounts. Sold as used/parts because I cannot test the air pressure plate to see if it closes and actuates because I do not have a compressor or air tank.  Plugged in and the platen got warm.  It was operational when put in storage years ago.  So, not tested and may need some adjustment or work.  IIRC it will do 35mm cardboard heat seal and 2 1/4 heat seal mounts.  The platen is in two parts -- when the insert is in it does 35mm and when removed it is larger to do 2 1/4. To be operational it will need heat seal mounts.  It may do the Byers compression plastic mounts that have the fold over pins with the heat off.  I could not find any on line info or pix or instructions.  Please no returns on this heavy item.  thanks and ask questions before bidding --make offer by messages.  Heavy -- will be costly to ship.
