| Notes | We have received a picture similar to Sentinel model 108A from a set in Switzerland. Yet we could not find this model here in any source in the US we only assume that it is an export model. The original schematic was drawn on January 21, 1931, by Leonard Tulauskas for model 108 chassis, used by the Sentinel also for the Super Midget 108A. |
