One of the truely scarce accessories from the early period. It looks much like the early No. 100, but the main frame did lift and drop just as the train arrived. About the only difference I've been able to find in the few examples that have survived is in the way IVES painted the lake beneath the bridge.

The example above and below has a blue/white litho on the rail. The one pictured at the top of this page is red/white.
