For a short time the racers had sales number 23. These models were cast in lead. The casting had no driver, 4 small studs as exhaust, no racing number. Several colours can be found on these models. Some had the hubs painted in the same colour as the body. In my collection White with white hubs and Orange with orange hubs. See pictures.
This casting was also made in zamac as I have one in my collection. To me it is not clear when this model was in production, 1934 or early 1935. Any suggestions?
