Brass throughout, except for nose screw which is dark metal. Soldering on underside of tail section no longer solid, but both tail pieces slide easily and firmly into place. Wing with screw adjustment will swivel for curved edge placement in front or back – see last photo. I don’t know age, but believe it to be pre-WWII. Wing span 8”, fusilage length 7 ½”, height to tail tip 3 ½”, weight 11.5 oz.
