Who makes Radio Shack's muffin fans?

[Father Haskell]

Specifically RS part# 273 - 242, 3" (80 mm) 120 VAC venturi axial
muffin
fan? Hard to find drawings for a mounting cutout without knowing the
maker.
Looks like I need an octagonal cutout for the least restricted
exhaust. A
simple, easy 3" circular cutout looks like it'll throttle the airflow.
