that’s an interesting lock,I’ve never seen that Logo before. From the looks of the lock I would think it was made during the art-deco period(1920’s-late 1930’s). Given the fact that it was made in Germany,I would think it was probably made for export to America which would have been a bigger market back then.. The lock is a simple warded lock which looks to have its origional key with it. Origionally it looks like the lock would have been painted with nickle plated accents,very common for products from that era. Nice lock none the less,which would look good in anyones collection, Mark🙁happy):
