I was looking at the 1957 ad on ebay today & it mentioned that the 150cc engine was available. When did they bring out the bigger version & how can you tell which version you have?
what magazines did they usually advertise in? I used to collect a lot of Life magazines, Popular Science, Popular Mechanix, etc., usually looking for studebaker ads & other neat project articles. If I knew which magazines they spent their ad dollars on, I'll start snooping thru my stash.
