Entex (also Nitto or M&B using the same molds) also made a 1:100 B-767-200 in addition to their 707-320B/C, 727-200, 737-200, and 747-100/200. The 747 kit was incredible, detailed right down to the anti-static wicks. Alas, no 757s. They also made some Douglas stuff: DC-3, DC-8-62, DC-9-40, DC-10-30.
VEB Plasticart of East Germany made 1:100 kits of mostly Soviet airliners. Not very good quality, but a good base to start from for kit bashers and detailers. The aircraft: An-12, An-24; Il-18, Il-62; Let-410; Tu-104, Tu-114, Tu-134, Tu-144, Tu-154, Yak-24P, Yak-40. Also a Dassault Mercure.
Revell/Lodela also made a 1:94 (or 1:96?) F-27 and Viscount.
