Dr. Drew, I believe I have read that the standard charge of 1oz English #6's were used to pattern test unless otherwise stated. Of course I am no expert. It will arrive in a case and I am hopeful that the charge card is present and that the extra springs are there, but I am preparing for the worst!
Mike, some other specs are: original 28" barrels, weight 6-9, file cut rib (not my preference), DT. Current chokes measure Modified, Extra Full per vendor. I'll be at the Southern, but unfortunately won't have the gun in hand. I seem to remember you have a Boss from this era as well. I hope you are enjoying it.
