Most Working Models are on that one wall, although there is an English Execution on the other side of the room. I have 3 rooms of games, total of 2,500 square feet, over 100 machines. Separated into a 1930's penny arcade theme (1896-1945), with the non-US ones in the side room (working models, Ruffler & Walker 2-player racers etc) and a downstairs area in a 1960's arcade theme (1940-1975). The Indian Fakir, Charlie and Mabel, and English Execution all came indirectly or directly from Todd's collection in 2013-2015. I would say the Indian Fakir is older, 40's or 50's, and Charlie is not as old, could be 50's but I would guess 60's based on how they were converted and materials used.
