Tape measure across the twin bores of an aluminum intake casting…

Close-up of a yellow Trophy "Made in U.S.A." tape measure laid across the mounting flange of an aluminum intake or throttle-body casting to gauge the spacing between two round bores. The part shows bare machined aluminum with staining and corrosion around the ports and bolt holes, photographed on a rusty work surface with the tape reading between the 3- and 4-inch marks.
