Serial Number 20359595 was reported as inaccurate.

Note: mine says double roller between the small gear
lock (?) and large gear. Does not say barrel
bridge or train bridge.
Curator Response: "Train Bridge" and "Barrel Bridge" are simply labels on the movement diagram. These do not appear etched on the movement.
