Many years ago I visited the NCO's Mess at Baldonnel. There was a framed drawing of the SE5A there. The fuselage was red not maroon, the rudder stripes had orange to the fin and green to the rudder end, this often occured on the early types. The serial 11was shown displayed as roman numerals and was central on the fuselage.When the Mess was redecorated the picture disappeared.I believe that it had been there for a long time and was based on the memory of older Air Corps personnel. There was only one purchased. HTH
