From a survey of my library and online sources I have compiled what is undoubtedly a partial listing of tuners and receivers which were capable of receiving stereo simulcasts. Years in parenthesis are actual model years when known. To the OP: can you add your Philco model number and year? Anyone else know of other models I have overlooked?
The earliest models I have found are both from about 1955: the National Criterion and the H. H. Scott 330. I suspect that the model year may preceed the Sam’s Photofact date by a year or so. In which case 1959 appears to be the year that most manufacturers jumped on the simulcast bandwagon. I even ran across a few tuners with an MPX-out connection from the mid-to-late 50s, well before that became a reality. There are also a number of tuners and receivers from after the FCC’s decision on MPX with simulcast receiving capability. This all seems to me to indicate quite a bit of confusion as to the future of stereo broadcasting from the late 50s well into the early 60s.
The only mention of FM-FM I have been able to find is in a description of the Fisher FM-100 in the Sept. 1959 issue of Electronics World:
And some terminology clarifications from the Oct. 1958 issue of Radio & TV News:

Don't know anything about the AM/FM stereo combination thing, but do recall lugging my fathers set up to my older brothers room for some two FM station quadraphonic simalcast stuff. Pretty cool, because one station was classical and the other indy rock, so quite the assortment. Quad really never caught on back then, so guess were calling it home theater today.
Assuming it's got a built in FM multiplex decoder, yes. Modern ones do.

AM/FM simulcast stereo was used again in the 80s (and my memory can't pin it down further) when a show called FRIDAY NIGHT VIDEOS was on NBC (as I recall) sort of like MTV but on network channel. It used the TV for one channel and you tuned the other channel, an FM station, in on your stereo. It worked well (i.e. - sounded good) but did not last long as stereo sound appeared on TVs sometime soon after they started FNV show. Swamp Daddy

This simulcast used FM Stereo for Stereo audio. Also, back in the day many PBS symphony broadcasts and opera broadcasts were simulcast on NPR affiliates for Stereo audio to be available.
That AM/FM miscegenation was dead and buried by the early 70's and it's bones were pretty much decomposed by the 80's.
They did some Saturday night rock concerts via "simulcast" in the early 70's but they didn't use AM. FM stereo as we know it today was already THE standard by then. It pretty much was by the mid 60's. They simply played the audio over a regular FM stereo station. No AM involved.
