My brother's music teacher was from Germany and gave me this phone about 20 yrs ago. She said her father used this phone at his place of business. Date is unknown, but it works fine, althought the numbering on the dial is opposite of American dial phones. I found out through an e-mail that this phone is Norwegian, most likely from Oslo, Norway. I would like to thank Steffen Froschle for the information. Dankeshoen Steffen!
