I have recently finished restoring my old dogtag machine. It involved some serious cleaning, lubricating, adjustments, and a little machining. I can now punch out dog tags for anyone wishing to have a set. I can print up to five lines, 16 characters (including spaces) per line. One complete set includes:
*two stainless dog tags
*two chains, 24", 4"
*two rubber silencers
The cost is 7.50 a set, shipping is included. When I was in the service, I remember the armorers strapped dog tags on barrels to identify what barrel went with what gun. Thanks for looking. PM if interested.
