Googling the type got zero hits. Hope someone knows something about
these.

That type of cast frame is the form that Goodmans (when they were still
a respected speaker company!) used for the later versions (around 1970)
of the Audiom 51/61 range and the Axiom 201/301. (If they are 12" that
is, the 15" unit was the Audiom 81)

These were the hi-fi versions with a plastic roll surround.

You missed out an adjective.
It should be "dreadful plastic roll surround."
I don't know what plastic Goodmans used but it shrinks over time and
ends up flat, which does wonders for the compliance and xmax.
