Per ASME Y14.35 standard, these are full lists of allowed letters to serve as revisions and view labels on drawings. There are two choices. The pre-2014 list contains all single and double digit revision letters. The current list (as of 2014) contains all single, double and triple digit revision letters. Omitted are the letters I, O, Q, S, X and Z. File format is Excel, from which the list may be readily copied.
