This question came up as a Google result... when I was searching for history on the Astron brand.

AFAIK, they are rebranded Sigma lenses. I have an Astron branded 28-70 f3.5, and some Sigma's from the same era, items like the knurled grip for the Iris ring, rubber grips, machined points in the bayonet end, are all identical between the Astron and the Sigma units.
