Need Model and year for 50's Evinrude

[smokin gun]

I was hoping someone could give me a model and year for these three old outboards I bought at an estate sale. I've searched the internet and the only thing I can find is I need to buy a book (The Old Outboard Book) that's $30 to find them. I guess I will if no one here can help.

Evinrude - ser# 7520-05576, 7.5HP (need model and year)
Evinrude - ser# 7522-09573, 7.5HP (need model and year)
Evinrude - ser# 15016-10759 (need HP, model, and year)

Thank you guys in advance.

$30 for the old onboard book would be an excellent investment anyway. Huge amt. of info. there.
