Bentley / Mr Barrington} is struck through) " " EFC. [STAMP] ORIGINAL RE 3/19 GEAR BOX. [HANDWRITTEN] 3Y20 Referring to the thickness of the casing of the 3/19 gear box, I think this is generally shewn on the three schemes sent to you of this box as .250". Would you kindly note that we should make this dimension .200". The casting will come out naturally thicker than this by the amount added by the operations of the foundry.
