Hello Steve, There was the A- the A-3, A-4, A-5, and A-6, The last of the A,s that Aeolian built was the A,5. I ask Elmer and Allan Brooks in 77 why they went back to the A-5. I never got a clear answer There may have been the A,-1 and A,2 I can not speak to this as I have never seen one. Jack Wyatt Dallas Chapter In a message dated 4/13/2011 4:19:04 P.M.
