Montgomery Ward and CESTAD
From what has been gathered thus far, it seems that Montgomery Ward (WARD) sold the trikes under their name brand from 1971-75 give or take.
From 1974 and on, Central States Tool and Die sold the trikes under their banner.
The assumption is that WARD liquidated their inventory in 1975 as CESTAD took over the various models.
