I noticed in my first post that my pictures were blurry when expanded, so I've sent a second set of pictures.

TPUTI I is printed on an arm on the top side.
41013, 41016, 41010B, 31881 are stamped on the arms on the bottom.
Made in the U.S.A, 05/01/01, and 05:55 are on the bottom of the housing.

See our 39-239B or its stainless steel variant, the 39-239C . Look over the dimensions to see if this could work for you. For a new handle set and cover, see either our 39-451 or 39-375 . For a new Pivot Slide, see the 39-536 .
