the book
Intermdeiate Military Vehicle Modeling by Osprey, manual No. 5, shows step-by-step pics of the build ups of both of these vehicles. The author seems a little high-nosed to me the way he describes how he, in his all-mighty, god-commanding position, wants it to be built by everyone else, but he does offer some very nice shots of the platforms, interiors, mounts and guns of both vehicles. and some of the extra detialing ideas are fantastic. you really should check it out.
dont know how much I got it for, but for reference, its got a pic of a panther on the cover, and the series editor is Jerry Scutts. hope it helps.
BTW- u can almost surely get the book from ur local house-o-hobbies, or from online form a store or auction place thingy.
