Double triggers are not all the hard to figure out....And it is highly unlikely you will find a good small gauge Parker or Fox for $2000.
Many good suggestions here. However, if you want to honor the old time Georgia Quail traditions….it will be a Parker or Fox.
You are right on all counts, although a Sterlingworth isn't too far out of budget if you settle for 2-1/2 inch chambers. They have gone up a good bit since I last looked.
