Lear 55 is a good bit taller, and possibly wider, than a Lear 35/36 that the Hasegawa/Revell kit represents (note, for those inclined to do lots of cutting, trimming, and PSR, the 35/36 fuselage can be shortened, if sectioned in the right place, and combined with the wings and engines of the IMC/Testors 23/24 to allow a Lear 25 to be modelled - more info and details if requested).
