Duplicating Axle Markings

While cleaning up the axle from my project, I found some factory alphanumeric markings I would like to replicate. I am not creating a concours restoration, just would like to preserve as much originality as possible.

Has anyone here had any success in creating a rubber stamp to recreate these markings? How did you do it? It appears that the markings are "G14" and "129V". Anyone know what these might mean? Thanks in advance for any help! L8r
