This was an exciting discovery made a few years ago at Dave Churchman’s warehouse. It’s a pantograph router cut block (actually, it’s three blocks joined together; see below) cut from end grain wood. The circular Hamilton Mfg. Co. imprint, clearly visible on the back, dates the block to 1889–1891. The dimensions are 31p6 x 42p0. This is read, 31 picas 6 points tall by 42 picas wide. In inches it measures 5.25 x 7.
