At 1/4" thick, there's a chance it's a DF32 platter.  I don't remember
how large the hub hole is, but at first glance, and with the PDP-8
suggestion, that's what I'd have to guess.

I have never seen  an RF08 platter, so I don't know how physically
similar they are.

One thing to check for - is there a band of tape or other blacking
material around the rim of the disk with a gap of a few mm?  The DF32
has just such a gap for the rotation sensor.  Not sure about the RF08.
