Charter Arms Ar7 Serial Numbers

I have to give the people at Charter Arms a real thumbs up. They never say die. Had a couple early ones years ago and even now have a vintage 3' gloss blue Bulldog. Stayed away from the Charco stuff. Now they are back and doing well especially in this economy.
I'm shopping for a NIB Charter Arms stainless .44 Bulldog but the various postings of 'new' .44's show different grips, some with metal medallions on the rubber, some with just pressed medallions on the rubber; some with the name Bulldog Pug, some just Bulldog. And, so on. Is there any reference out there that describes the differences in models via a timeline? I'm guessing changes were made as time moved on in the past 11 or 12 years since they have been back, and those changes can help date one of the new ones for me.
Any ideas? Thank you!

The big contribution Charter Arms made to the AR-7 story was the addition of the Explorer II pistol version of the AR-7. It resembled a broom-handle Mauser. The receiver had a built-in pistol grip with no provision for the rifle stock (the internal parts are interchangeable between rifle and pistol).
