NO d 1543
During my Navy career I have had occasion to observe (and perform) the short-cut of while making machine lettering not stopping to change letters and do another alignment and set up for one letter. Point being I think someone was using the machine engraver to letter these revolvers and did not stop to set up a lower case "d" and just kept going with the all caps NOD instead of NOd. Short cut, time saver, get the work out, measure. I do add my thought that the marking is as SPEEDO2 suggests. The shipbuilding company marked the revolvers with the Secretary of the Navy Contract Number NOd 1534 as an accounting tool. Great question, great discussion.
