I have some doubts about three cars that raced at Indy in 1955:
according to 4 different sources, the cars appeared with diferent makes. The sources are Phil Harms, Popely's "Indianapolis 500 Chronicle", indy500.com (photo section) and indy500.com (boxscores). The cars are:
#37 Dr. Sabourin Spl. (Eddie Russo)
Harms, Popely and photo section - it's a Pawl-Offy
official boxscore - it's a Allen-Offy
#71 Martin Bros. Spl. (Al Herman)
Harms and boxscore - Silnes-Offy
photos and Popely - Curtis-Offy
#83 McNamara Spl. (Eddie Johnson)
indy500.com (both sections) and Popely - it's a Trevis-Offy
Harms - it's a Turner-Offy
Any ideas of who's right and who's wrong?
(please note that in two cases the indy500.com gives two different cars in their sections.

Thanks
