The MD-3 ground power unit was designed to start up engines of such USAF aircraft as were the B-47, T-33 and many others and was in use throughout the 50s and 60s. The master pattern of the model was designed using 3D software and printed out on a 3D printer. The resin cast parts come with a fret of photo etched details and a sheet of decals. The MD-3 kit is already available in 1/72 (item 7422), 1/48 (item 8058) and now finally also in 1/32.
