Checked the speedo on 11730 and it is the same as the one I pictured. It is dated as with, in what i would say, is the correct range for a speedo for my DOD- markings of K2 ring a bell but i`d need to recheck. All my other guages also have the same dating as the speedo.
Bob- sorry, forgot to check the numbers, but as luke said, they are numbers- part number i guess. Apart from the speed indications, these are the only markings on the face.
