Those are all older radios that have been 'out-of-stock' in the surplus business for half a decade. That being said, they do show up on e-Bay every now and then, and Fair Radio in Ohio and Haynie Electric in Texas might be able to locate one or two. Might also try Murphy Surplus in El Cajon, CA to see if he has any unlisted ones. BTW, there is a lot more to setting one of these up than just the parts you listed. Actual antenna, control cable, RF cable, handset, headset, bases for the radios and the receiver. And you could swap an RT-246 for one of the RT-524's, since the only legal amateur band is the six meter (51 Mhz) allocation. Most trying to 'look' authentic use a shell and put a modern radio inside with a much wider range of frequencies available.
