I don't have a 23" Sports to compare, but I can tell you that the DL-1 from the 60s-80s was only available in 22" and 24" models. My 24" DL-1, from the front of the tire to the end of the rear reflector, is about 6'5" in length (23" top tube). By comparison, my girlfriend's 21" Sports is 5'10" in length, including the rear reflector (20.5" where a top tube would be).
The phantom top tube on the 22" DL-1L is 21". I'd guess it's about the same ratio as a Sports.
