Three Inch 66 Which Distributor?

[xfarfuldog]

I picked up another 3" 66 today. It is a 66-3 with prefix BPR. My other one is AFL which I believe is an Ashland Shooting Supplies model. I sold another 3" 66 maybe a year ago with a prefix I thought was out of I believe Alabama. Anyone have a list of those distributors for the 3" 66? Or specifically my BPR?
I traded a particularly sweet 2" model 10 for my newest 66.

The triple alpha BPR serial indicates probable 1993 production. AFL is likely 1985. I'm unaware of any serial prefix being allocated to a specific distributor.

The triple alpha serials were introduced '81-'83. From AAA onward.

Not sure, but I believe all of those went through Ashland as their distributor exclusive. Just different batches. Lew Horton was another that sold exclusives. It's a great gun.
