Pierce Airo was the original name for DeWald, it was not a private label. The chassis in the set linked to is similar but not quite the same. I don't think the mystery radio is a U.S Radio and TV/Apex built set either, those seem to have data plates riveted to the back of the chassis, however the tuning condenser looks the same, so whomever it was used the same suppliers.
