Here's a partial from "Erecting Card, Narrow Gauge National Coal Dumps Car Numbers 700-799.....3772.....C-421.....December 13, 1905" DPL location: "Equipment drawings - Rg39;Sec5;Sf4;Tube1" showing the end lever arrangement. I was in error yesterday (3 mistakes in 3 days across 2 forums, losing my touch), the early drop bottoms were hinged from the center not the sides as I stated.
Only pertinent to the C&S in that they would have existed in the time period covered by the C&S/D&RG interchange topic. Would really like to see if a photo(s) exists of the equally rare early D&RG 1250-1499 dump gons which were later rebuilt to regular high sides, would have been in the same time frame.
