tdonovanj Posted July 21, 2021 Share Posted July 21, 2021 Just wondering what the significance of these letters are? In addition to the D and K there is also USA stamped twice and at the top of each back are the serial numbers 144X552 and 144X553. These are (I think) late 1982 H1s as they do have the E2 XO. Although the number "2" is stamped next to the red E rather than being printed. Any insight on the D and K would be appreciated!

MC39693 Posted July 21, 2021 Share Posted July 21, 2021 welcome to the forum. @HDBRbuilder can elaborate, but my understanding is they are initials of the cabinet makers.

Those are the initials of either the sander or woodworker that built the pair. @HDBRbuilder might know to whom those belong. Quote Link to comment Share on other sites More sharing options...
