Greetings,
I am interested in learning some background info on the firm of Georg Rieder (Munich), and any information is thankfully accepted.

Essentially what I'd like to know is whether this firm did actually manufactured materials, or served entirely as a distributor of products from manufacturers.

What did they manufacture or distribute.

How large was this company.

I have tried various searches with positive hits typically discussing a product distributed by them (no history/info on the firm).
Thanks again in advance for any kind assistance.
Don
