This photo was sent to me by Amanda Stevenson, Curator at the Museum of Printing History in Houston, Texas who asked me to identify the press in the background. I recognized it as a Claybourn hand proof press made in Milwaukee, Wisconsin circa 1926. There should be a nameplate on the operator’s side and the name “Claybourn” cast into the base. Coincidentially, I have been working on an update on the Claybourn page of this website. Thanks to Eric Holub for lending me his splendid Claybourn catalog. From these catalog images one can see that the Claybourn resemble Hacker presses and appear to be as solidly constructed, and like other contemporary Vandercook competitors, they have reciprocating beds and stationary carriages.
Note the green rollers. Amanda says their oozing, so they must be made of polyurethane. Does anyone have a effective non-toxic cleanup solution?
Also, can anyone identify the wooden machine in the foreground?
