⭕ Side-plate diameter maybe 3-3/16; pillar length maybe 1-1/16 (inside plate face to face). Stamped on the foot 36X and V39X which I think dates it to 1929. Side disk has the July 14, 96 patent mark.

It should be evident the condition is astounding.

It shows minor wear but absolutely no indication of hard use or abuse. Even the red dots for the indicator are still vibrant. The inside edges of the center of the aluminum foot are discolored but upon careful feel it is clear it is only light discoloration and not pitting - and that includes the entire foot. I should also say I dont see any indication the foot has been tampered with or changed from its original configuration.

Its likely this hasnt been worked on, or serviced, for a long time. The original case is marked 2/0 and has done a fine job of protection.
