Anyone out there that can identify (i.e. size & arrangement(IE: 1Kx1)
and technology (i.e. Dynamic vs Static)) of some old RAM IC's?

The parts are made by National, circa 1973. Part numbers are:

MM4260 and MM5260

They are 16-pin plastic DIPs.

These are found on an old memory board that is organized in four groups
of 5 chips, with 3 4260's and 2 5260's in each group of 5.
