Well, the meter looks pretty nice
That is a very heavy radio and is pretty common. I paid $20 for RBK #1 which looked perfect and I was given a second one, less case, at a hamfest last year.
These radios are a S-36 variant and are probably the best constructed Hallicrafters receivers. It has the same attractively patterned front panel as the SX-28. They do a nice job on FM broadcast and have a great sounding audio section. This Navy version has an additional "radiation suppressor" stage between the antenna input and first RF amp and it absolutely kills the sensitivity. It is easy to bypass and you end up with a spare acorn tube in the process. Combined with the SX-28A by the military during WWII the pair provided coverage from the AM BCB through 143 Mhz. By itself the RBK covers 27 through 143 Mhz. in AM, wide band FM, and CW modes.
