Just to close this one off, a bit of "Kit History".
When Monogram first released the kit, it contained all the bits to do the atom bomber including a miniature set of bombs (Fat Boy & Little Boy.) What it lacked was the uncuffed props used for most of the non-nuke planes - Pretty much restricted which schemes could be used... so had to wait for KMC (and others) to come out with correct props before we could do some of those great artwork birds. (Yes, I know you could carve away the cuffs - for all 16 blades!) Later, in one of the Revellogram reissues, the kit was molded to have both styles of props, which is what you get in the latest releases.
If anyone ever wants to see the difference between what Revell "was" and Monogram's standard, compare the 1:48 scale B-17E (REV) to the 1:48 B-17G (Mono.) The major parts are essentially interchangeable (leading me to believe there was some industrial espionage going on by Revell) but the interior detailing was much more simplified in the Revell kit. Still, makes for one of the easiest kit-bashes around - though a bit pricey!
Monogram always had good, solid kits with sometimes even great detail, especially after their "modern" era. I suppose that is why Revell is able to keep reissuing them, sometimes tweaking them. Still great value for the money, and "real modeler" kits that will require care and occasionally adjustment to get a good fit. Nothing lost in learning to "fettle" the parts, gets you ready for Classic Airframes (and other makers) kits.
Sorry, waning nostaligic... Robert
