Keystone Telephone Company of Philadelphia Dial Desk Stand

c.1911-1923 - I display this deskstand mainly because it was found with a great earlier style Mercedes dial equipped with an original very early number face made from thick paper material rather than the familiar porcelain. The paper has held up surprisingly well for its age.

Additionally, the fingerwheel is stamped "AUTO. ELEC. PAT. 597062 U.S.A."

For comparison, I added the above pictures of an all original, early Automatic Electric dial (same as on the stick to left). They have the same paper dial face, though this one is complete with the protective glass covering. Also, this one has the original number card and "X" shaped retainer (which predated the retainer shaped like a Mercedes emblem).


When used with Keystone phones, the number card/retainer would be replaced by Keystone's distinctive porcelain disc. These earlier "Mercedes" type dials are difficult to find, especially with the original glass still intact.

Keystone Lineman/Repairman Test Set

c. 1913ish - Here is an example of a Keystone Lineman/Repairman Test Set. These type sets are not highly collectable, but I am partial to anything Keystone. It seems a bit primitive, and what I find interesting is that it has a Kellogg receiver which is original to the set as used and found. Although in fair condition, obviously this set saw some hard usage.
