This is Berkeley's 1953?  large balsa Helioplane model kit.  There is some assembly.  I aint gonna try and inventory this---if anything is missing and you have the skills to build then...then you certainly have the skills to fabricate balsa parts from the plans!  Not sure if the 2nd main wheel is included----didnt bother to empty out the parts.  

Original decals are shown---I have started to make diigitally edited and color corrected reproductions of the decals [inkjet printed water slide].  The reproductions shown are a work in progress.  if you are interested we can negotiate ap rice!  they are LARGE!
