I didn't include the grip choice as that wasn't normally an "extra cost" option.
I've certainly seen all the variations. I've got a 20-gauge Ithaca built Lefever A Grade with single trigger, beavertail, Ithaca bridge-trestle recoil pad and twin ivory sights, but no ejectors; and an Ansley H. Fox A-Grade 16-gauge with double triggers extractors and a beavertail. The order for that Fox was quite specific in all sorts of details -- straight grip, wavey grain in the wood, monogram on the trigger guard, rib as narrow as practicable, right barrel 50% left barrel 60%, but just double triggers and plain extractors.
A gun I've always remembered as very interesting was a very late big 32-inch 12-gauge Parker Bros. VH-Grade with its only option a vent rib. I guess somebody decided he wanted a vent rib Parker and that was as cheap as he could get into one.
