I remembered three more--Otaki (also have it in Airfix and AMT boxes, maybe an ARII one too), Fujimi (which is actually 1/50), and Idea, which is a VERY poor Korean copy of the Fujimi.
I just got a second CA P-51H last year, which gives me courage to try to build one of them. I've got the HPM P-51H all built, painted, and decalled, only needs final detailing and assembly to be finished. And it's been that way for at least 4 years. I hate when that happens.
I also have a built Aurora P-51H that I"m gonna do as a gear-up "desk model." Should be an interesting project.
I've actually BUILT (1/48 P-51Ds) one Hawk, one Revell, one Bandai, one Otaki, and three Monograms.
