Hello all ...Bauer made these for several years with different suppliers of track ... and perhaps cars ... if you look at the ad from 1928 ..the car looks like your newly found car
the later units occupy a smaller foot print ... basically a circle combining the tower ..where as the early models the circle is removed from the tower ... fun toy no doubt survival rate was low . Cheers Carey
PS; I do have two Bauers so if someone needs one let me know
