Found a source for 7360 and it is some interest among my friends for
using this tube in HF receivers, particularly for 80 and 40m
It was mentioned an article by W2PUL(?) in QST using a high current
twin triode as RF amplifier.
Have seen the SSR-1 rx schematics. Is some more notes available on
some sites for a modern version of receiver using these devices? I
suspect some parts of the receiver could be improved over the practice
used in the 60's
Any suggestions?

The latest article I can think of seeing in print was February 1972.
I may have the date wrong. It was by one of the QST staff members
but not Doug DeMaw; I want to say Doug Blakeslee.

It was a 3.5MHz receiver with a 455KHz design, hardly cutting edge.
But it was intended for strong signal handling, so he used a tube
in the RF stage that had higher current handling. He half jokingly
suggested using an 807 in that stage.

A lot of those articles using the 7360 used no RF stage, which is
why you often saw a signal frequency Q-multiplier, to aid in image
recection. Of course, by the time the 7360 was put to use, HF range
IF filters were available so many of the receivers used an IF in
the 5 or 9MHz range.

Ray Moore had some articles in Ham Radio in 1972 and 1973 about
receiver design, and the introductory piece covered mixers including
the 7360, and then he had a "construction" article on a fancy AM
BCB receiver, that used a 7360.

Maybe some work was done with the mixer after that, but it pretty much
faded from view from that point on.
