Machined foundry pattern cut into pink tooling board and framed in laminated wood, standing on a bench in a shop and shaped as the cavity for an engine front timing cover. The relief shows cam and crank snout bosses, twin recessed cutouts and bolt-boss detail, with "J&I" written on the bench at lower right.
