Tom, I own a 28 ga., 4710XX numbered ICD 4E and I love it. I guess the fact that they only made fewer than 300 guns in total explains why you don't hear much about them. Mine is BT/PG double triggers. It weighed 5# 15 oz when I bought it but was a bit muzzle light. I removed almost 3 oz. of wood from the butt (scary job!), had the chokes opened to cyl/IC (they were an unmarked mod/I.mod when I got it) and it is now a perfect weight and balance for me for grouse, of which it has accounted for around a dozen already this season. Thanks for this thread; they are fun to discuss!
Joe
