Welcome to the club looking for 22 PAM Logo buckles (see my Sig)
I even tried DSN with no luck. I managed to acquire 1 ARD style from a member here (which I think you are looking for), but finding branded Pre-V 22's is a challenge.
Good luck, if you find a source, please share, as will I. I have even taken to eBay looking for Gen buckles.
When in doubt use a Google "Site" search:
Goto google and type: site:rwgforum.com 1665
Here was my result: http://www.google.com/#hl=en&source=hp&q=site%3Arwgforum.com+1665&aq=f&aqi=&oq=&fp=e8d6ef47431c6a4a

Personally, I find the "standard rep AR" too blue. The modern gens have what appears to be a really good quality single AR. Someone correct me if I am wrong.
Just my opinion, but, I would tend to say go NO AR or go Chief AR.
I Cheif AR'd my 112h and 177h, and the pure clarity, almost impossibly to see dk purple/brownish AR IMHO makes it appear more plausibly gen. This is based on the quality the crystal takes on. If someone is going to call me out for "too good / better than gen AR", then they are probably a member here and better say so.
I can't say for sure, but I can add that the older A7750 21.6's were the same hand size as Gen 7750's. That said the sizes for A7750 should be: 2.00/1.20/.26/.20. .26 being the sweep hand, and .20 being sub-dials.
From my observation of real, hard core, Scuba Divers, I would say 80%+ actually wear Seiko and Citizen Dive watches. Despite the fact Rolex, Omega, Doxa, etc, are normally thought of when thinking about diving.
I also have 3 family members who are pilots. They all wear Citizen's, not Breitlings.
Lead is only going to be a hazard if you ingest it. I am sure there is lead based paint used in some of the dials, or inserts. Again, non-issue since the dial is sealed off. Just don't chew on your bezel, or let your kids chew on your watch.
