A Team of Keystones

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."


Differences of Keystone Dial Stick Necks-Click for larger View

I have found 3 styles of dial sticks, having just subtle differences to do with a ring/band located at the bottom edge of the switch-hook cutout. The purpose of the ring is likely for reinforcement. With each change, there are differences to the pileup inside as well, the earliest being much more primitive than the last.

What appears to be the most common and likely the last produced is just a straight shaft with no ring (left). Likely an earlier style having a ring stamped into the shaft which is possible the rarest (center). Finally, the earliest style having a steel band attached to the outside of the shaft (right). Very similar to the much earlier manual Phila model 43.

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 original protective glass covering. Also, this one has the original number card and "+" shaped retainer. Likely, this number card and retainer was used on #50 coin collectors.
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 very different Keystone Lineman/Repairman Test Set. Usually, these type sets are not highly collectable, but I am partial to anything Keystone. It seems a bit primitive, and interesting the watch case style receiver is manufactured by Kellogg, yet has a Keystone marked cap on the transmitter. Although the Keystone cap looks identical to (and could be) a Keystone receiver cap, the cap threads will not fit any of my Keystone receivers.  Although in fair condition, obviously this set saw some hard usage.
