Good morning VDH. I became the proud owner of a DA-Navy Approved late yesterday, thank you kworkman for letting me buy the reg from you, but am found to be lacking the in the information department. I'm trying to narrow down the year and the rarity of the unit but am having some issues. According to the Regulator Id section the quickest way to ID the reg is the label, either blue or yellow, however the label is pretty degraded but there appears to be fleck of yellow in certain sections(Fig.1), just not enough to be definitive. I have yet to open it up yet, that's todays chore if work permits. Are there any mechanical/physical attributes that might help me narrow down the year?
