For those who might find such information to be of benefit, please know that several Weinmann catalogs as well as vintage examples of their advertising copy are now available for public perusal at Velo-Pages. This information may be accessed directly using the following convenient link:

For whatever it may be worth, the 1983 Weinmann Silver Jubilee 50th Anniversary catalog also includes a corporate overview and a bit of their history (...nowhere near as much as what Shimano put forth during any one of their significant anniversary years, but still it is more Weinmann background information than one is likely to find readily available elsewhere).
