I know that there are some regular layout Model Ms with thicker back-plates, but are there any SSKs that have them too?

TBH I've never seen a PC/XT or PC/AT version of an SSK. The earliest I've encountered is an 1987, and it seems pretty comparable with another one from 1992.

my 87 m has a thick plate, so maybe the ssks from 87 have the same plate.

Specify "thick." You mean the cobalt rainbow plate?
I'd be surprised if any had them, there aren't even any square badge SSKs that we know of. Although I'm not the <100% expert here xD .

if a square badge ssk shows up I call dibs

I don't know how thick, but my IBM SSK is quite a bit heavier than my Lexmark SSK.
I measured them once, the post should be around here somewhere.

It would be interesting to try to narrow down the date range for the switch-over to lighter plates. Apparently each plant ran their old stock out and went to the new ones at different times.
The only shiny yellow ones that I have had were 1985s, but I have had the heavy gray ones into 1987. But my pre-1989 sample range is under a dozen.

My '87 '1406 has the cobalt plate, but that was made in Greenock of course, not one of the US plants. I suspect it was one of the last ones made with it.

It makes me think they just took leftover Model F plates and punched holes through them.

But none of the Model Fs are the same dimension as a Model M Oo .

But they did use the same sticker templates. Five signature fields for five stages of assembly and QC, and the F had all five signed and M usually three.

M usually had 4 signed, as the controller was not permanently attached as it was on the F's.
But that's not relevant to reuse of the backplates. Completely different dimensions.

Doubt that, but whatever cleaning/tank/oven/coating equipment was used on the F plates behind the PCBs was probably used on the early Ms.
