Heyer Conqueror Mark Six (Model 1770) Stencil Duplicator and Heyer Conqueror Paper Folder, purchased as a “matched pair” for the expedient reason that there’s only one document feed tray shared between the two machines.
The 1964 Heyer catalog found in the digital library features the paper folder (bottom image), though the Mark Six is not included here (it does bear a slight resemblance to the spirit duplicator in the top image).
Unfortunately, the duplicator suffered damage during shipping. From what I can tell, as I haven’t sat down with the machine to confirm function, the damage is cosmetic. The box in which it was packed also contained the heavy-duty paper feed trays that gouged into the frame and rubber gasket and bent the aluminum drum cover. The drum stand was also bent – severely enough that I figure that’s what did the majority of the damage to the duplicator.
What’s needed: I’ll give them both a good cleaning, set up their trays, and see if everything aligns correctly. The gouges are here to stay for the time being, but I’ve got to reshape the drum cover (I may take it to an autobody shop and see if they have any suggestions). I’ll be able to bend the drum stand back into shape. Then, just get some ink, paper, and stencils and it’s time to try them out!
