Thanks, Ludwig. A bit of background info is always nice.
Something I noticed on the flyer at the top. The price of those bikes was 330 to 340 Reichsmarks (Reichsmarken, I suppose, to the Deutsch).
I don't know how to compare Reichsmarks to Dollars. But, if I remember right, the old Deutschmark, just before the Euro, was worth about a half a Dollar.
If so, and if the Marks are comparable, then that Torpedo cost about 2/3 of what a Model T of a few years before would have cost. In America, anyway.
I'm not at all certain of my accuracy there. But I do get the feeling that those bikes were not inexpensive at all for the folks of that place and time.
