The APEX engines from early to mid-1930’s America constituted one of the earliest, most elusive and most ephemeral model engine ranges to appear in pre-WW2 America. This range came and went so quickly that not much has been written about it in the past. The best that I’ve been able to do is bring together information gleaned from the various sources to create at least an outline of the history of this range. Better do something than nothing! The resulting article on the APEX range may be found elsewhere on this website.
