    The TBM discussion reminded me of something that's always puzzled me. The last letter in such designations signified the manufacturer, but the Navy usually assigned a unique letter to each maker. That's why Brewster had to be A (B was Boeing) or Grumman F (G was Goodyear). So why did they use M for both General Motors (Eastern Aircraft division) and Martin?

    Because no one would confuse an Avenger built by GMC with a large patrol boat built by Marton.
