Stockholm's KH
This wall telephone, serial number 137836 from year 1897, was made for Stockholms Almänna Telefon by L.M.Ericsson. The Stockholms Almänna Telefon katalog describes it as Model KH.

It can be seen that the Phone has a sun like brass disc in the center of it's crown.

Aktiebolaget Telefonfabriken Stockholm ("The Telephone Factory") was established in 1896 and in 1902 L.M.Ericsson bought  the company.
When bought the phone was missing the battery cover, which I made new and painted like the original one.

The remainder of the phone is in unrestored and in "as found" condition.
