Famous from the Battle Of Britain the He 110 was the mainstay bomber in the Luftwaffe during WWII. If you want to learn more about the plane I recommend the Wikipedia article.
There are two base kits (with new tooling). Monogram did one in 1994, Heinkel He 111 German Bomber, it has since been re-released by Monogram, Revell, Pro Modeller and Hasegawa with different new parts and decals. In 2017 ICM released a new tooling of the He 111H-3, they have since re-released it three times in different versions with new parts. The later kit from ICM is a well moulded kit with good detailing.
