I have an MRT-55 in the basement with the serial number of "SAMPLE". I also have Greg's old TR-5 which has a serial number of "117" (17 of 25 prototypes built). It has a high-power PA brick, as opposed to the production 90w version.
If I could have just one set of Collins gear, it would be an HF-380/451-S1 pair. The latter is rare as hell. It's along the same lines as the Drake TR-4310/R-4245 setup.
