The Bandai military kits are no longer made to my knowledge,so ya gotta go through adds in model magazines&ebay,model shows&swap meets...or a really,really good hoby store.I cant think of the Bandai kit(s) that (may) have been used on the Falcon....possibly the 8-Rad?To my knowledge...I think the 1/12 JPS&Yardley engine part(s) were used in a few places here&there( inside top rear L.H.S access pit) rear engine detail.? I think the 1/20 kit parts were the Ferrari 312BorT3(they have similar engine parts).The 1/20 Tyrrell,Yardley also,but Im not sure if all of those were made in 1/20 scale...but I think they were.I know in one of the upper rear access pits..actually the one Moe scannned above on this page has 1/20 parts in it..but I have'nt got the kit(s)...so Im left up to guessing.I think they are 1/20 Ferrari parts...look in yur Chronicals book..you can see'em plain as day.Looks like the the back end of what looks to be transmission housings w/struts attached..and some other suspension or front end parts.I can alwasy use help in i.ding parts.....it's not one of my strong points,and its frustraiting.Especially when I want to build,but cant because of lack of info,or my own limitatons/experience/means of extracting the info I need& being able to make it into tangable material.Anyway,keep coming back with what ya got....the more useful info the better..catch ya later-John
