Having a quick look in Engine Tune Up Manual and Service Specifications 1932 by The Canadian Automobile Chamber of Commerce, I see
Stromberg U2 used on
Chrysler "65" 1928 and 29
Chrysler "66" 1929
Dodge "DA" 1929
Durant "614' 1930
Durant "617" 1930
Durant "611" 1931
Durant "614" 1931 Durant info approved by Dominion Motors/
Franklin "130" 1929
Franklin 135- 137 1929
Hupmobile "A" 1929
Hupmobile "S" 1930
Hupmobile Centuary Six 1931
Studibaker "FC" 1929
Studibaker "53" 1930
Studibaker "54" 1931
Of course this doesn't take into consideration the US Durant cars 1930 612, 614 that also used the Stromberg U2.
