This is a vintage sales sheet from "Boyar-Schultz" advertising for their "Cross Slide Knurling and Thread Rolling Tool - Model SK," one page, printed on both sides, measures 8 1/2" x 11", and is undated but appears to be early 1950s vintage. Condition: There is slight corner handling, and the top edge has an indentation & light rust residue from a paper clip. See my listings for other unusual, interesting and fun vintage items. Multiple purchases are combined with a single postage charge. All items are shipped sleeved in plastic and packaged between sturdy cardboard.
