"Numbers do lie" comes as a hard truth to a Mathematician.
You probably noticed that part number SL16134 doesn't exist on sealife parts online. In fact none of the numbers there resemble 16134.
Welcome to the world of computers where numbers do lie all the time (but mostly because the users put the wrong numbers in). Also true of part listings and stock keeping units: e.g. I've a couple of HP monitors here in the office that have an HP part number for VESA mount bracket, with pictures and technical drawings, that does not exist in corporeal form in this universe. So it's not like Lenmar is an exception. Or SeaLife.
