You cite nose cone ( guns) deletion at both block -20 &-30 – BO. Freeman, B-17 … Story, places the change over at Blk -20 however my observation had long placed it at the new serial number run, i.e. block -30 based on observation. A recent, renewed string of observations again favors block -30 (42-50XX).
Recommend yo run your own review and if you reach the same conclusion, resolve the duplication and conflicting information by deleting the phrase about nose guns from block F-20-BO notes.
