Yours was likely made by Star mfg.
The ones by Star and Board Market are almost identical in every single way except the board Market dynamo speaker cutout is different. Build quality, the control panel key notch, base assembly etc are all exactly identical. This is why i believe these cabs were likely commissioned by AmeriCorp to their specific specs.
