Additional memo from Mr. Gumbinner 6 Stencil improvements and Speed-o-Print

Our tests showed excessive type filling.  I made a solution that was coated on one side by a coating unit installed at the back end of the coating tunnels which consisted only of nitrocellulose and a plasticizer.  As this coating had a lot of glare I had diatomaceous earth solution put in the middle of the drying tunnel which solved the problem.  For the lower price Polychrome label stencils this was added to the back coating solution.  Later when we made the stencils for the Gestetner duplicator we added an anti-static coating in the middle of the tunnel.  Mr. Halpern made an arrangement with Speed-O-Print that made a hand operated stencil duplicator and was located in a former Bell and Howell building on Larchmont Street, Chicago to take over their stencil coating and mounting facilities.  Speed-O-Print sales manager was Gibby Grant.  We moved their finishing equipment to Yonkers.  They had an 18 inch multigraph to print the heading and scale on the stencils.  The man who ran this press was brought to Yonkers.
