The 737-200 was a 737-100 with an extended fuselage, launched by an order from United Airlines in 1965 and entered service with the launch customer in April 1968.
Our model is very detailed, with low relief marks, surface lines, windows and antennas. It is cut into 3 scales, 1/72, 1/100 and 1/200. Have fun!
I recommend printing the 1/100 and 1/200 scale versions in resin. The 1/72 works great in FDM and resin.
