Thanks everyone.
It's always interesting to see these old adverts, you'd be amazed at some of them. Assuming the dealers know what would sell, a lot of cameras they lusted after in those days have disappeared.
Although the trio that appear in almost every advert were the Leica IIIa (with Summar), the Contax II (with Tessar) and Exakta. Usually there was a forth camera in the advert and they rang the changes between the Rolleiflex, Compas and Robot.
Other that the the magazines are pretty much as they are today. I could answer a lot of forum questions just by reprinting the 30's answers.
