Time to add some more stuff I'm currently trying to finish, and that's WiP for too long time.
Antonov An-24
An-24A - the first production version (of 1962) recognizable by single ventral tailfin and 8 passenger windows;
An-24B - improved version of 1966 with twin ventral tailfins (except for the first batch which had only one) and 9 passenger windows, An-24V was its export version;
An-24R/RV - further update of the design with TG-16 auxiliary power unit replaced with RU19A-300 auxiliary turbojet booster in right engine nacelle to improve short field performance;
An-24T - military transport version with ventral hatch in the rear fuselage. While an useful plane, hatch arrangement had significant shortcomings that led ultimately to creation of An-26. An-24T was further upgraded to An-24RT version with RU-19A-300 turbojet.
Besides these major versions, An-24 was base for many specialized derivatives built in short series, as well as many testbeds, flying laboratories, etc. for many of which sources are unfortunately too scarce to allow drawing them.
An-24LR Toros - ice patrol aircraft with two SLAR radar sets in large fairings on both sides of the fuselage,
An-24RR - NBC reconaissance aircraft with specialized equipment for radiation measurements,
An-24Rt. (also, quite confusingly RT) - a communications retlanslation aircraft, there was also airborne command post version An-24ShT for army-level commanders (replacement of earlier Il-14KSh), but finding any pictures of it is next to impossible.
An-24T Troyanda - flying testbed for ASW equipment.
These Polish and East German You essentially know, but they have been slightly modified (esp. regarding window arrangement), and Polish ones have been rearranged on the template.
An-26, An-30, An-32 and Chinese Y-7 are to follow soon.
