Welcome Pat -
Not sure about "on-line" info, but if you contact the Studebaker Museum, they'll have everything you ever wanted to know about your car. They may provide the cowl tag info for free, but for a small fee, they'll provide an accurate "window sticker", with all the info the car was sold with, maybe even the first owner.
http://www.studebakermuseum.org/The Studebaker Drivers Club is also a wealth of knowledge.
