So I decided to take a shot on post-WWII Soviet bombs (so long as available plan drawings will allow), and started off with the M-54 series of GP/HE bombs
Plans and data primarily taken from Yefim Gordon's Soviet/Russian Aircraft Weapons Since World War Two
and a product brochure from the Bazalt munitions company; additional data from a well-done, well-researched weapons mod pack for the flightsim game Strike Fighters 2
(hosted at the CombatAce website; haven't played that game for a long time). A few caveats include approximate colors ("navy gray"), and things getting dicey on the body diameter vs. fin span scaling on the 3000+ that I bit the bullet and just focused on the former's dimensions.
