There is that group of receivers that are very similar to the R-390. I already differentiated between the R-390 and the R-390A.
Some people include the R-398 in this family. It is a Collins 51-J, and has an IF of 500 kHz, I believe. The R-389 looks like an R-390, but tunes 15 - 1500 kHz. There where few produced, and one in good condition goes for about $1,500. Then there is the R-391. It is essentially a mechanically- driven, autotune R-390. Only a few of these were produced. I saw one, and I wouldn't have one. Then there is the R-392. This was supposedly built for use in military vehicles, and requires 24 - 26 VDC power. It is much lighter and about one-half the size of the R-390. The R-392 is an excellent receiver, but lacks the strong- signal overload capabilities of the R-390, and it lacks the R-390A's mechanical filters. That, in my mind, limits its utility as a serious receiver for "split" tuning. Finally, there is the R-748. It was designed and built for use aboard aircraft.
