ShiftPlusOne, the card in question, with the latest version of Raspbian on it, does not work with the new pi but does work with another (older) pi. This card is a Dolphin peripherals 16Gb class 10 SD card. This makes no sense to me.
I could look to fault the newer pi hardware, however it does work with other SD cards. I have tested it with two cards. One is a Dolphin card (as above) with RISC OS on it. The other is a Samsung card with an Adafruit OS on it (this is what I described in the OP as "an older image of Raspbian", so I was wrong there - to a beginner they look very simillar in the GUI, and the card is not mine so I was just informed of this error.)
The fact that the Dolphin brand card with RISC on it works seems to also rule out the idea that there may be a different card reader slot in the new pi hardware that is not compatible with this Dolphin brand for some reason. So I am stumped.
The only accurate concise conclusion I can reach so far is that the new pi does not run Raspbian OS. This seems unreasonable.
No (faint) green
flash suggests that the card is not making proper contact in the newer Pi's slot. Since the "Dolphin" brand is "untested" (in the sense that is does not appear in http://elinux.org/RPi_SD_cards
) and, given that the new Pi does work with an established and recommended brand (Samsung), I would suspect the card rather than the Raspbian image. Given that you have another card of that brand which does work, what about burning the newest Raspbian to that card (or, better still, try one of the more "well known" brands - I mainly use integral, Kingston, or Transcend cards, usually class 4). Currently there is a known issue with SanDisk ultra cards w.r.t. the NOOBS 1.3 installer, almost resolved but "final" testing is "in progress".

Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, A+ and a B2) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm
