I am finishing a 1901 Crescent number 31 and it came to me with a New Departure coaster hub on it's wooden rim. It's not marked A and there are no marks on the curved hubshell either but still fairly certain that's what it is. FWIW there is no grease port and there is a screw adjustment at the tip of the brakearm. At first I assumed it was a much later hub, then read this sticky and think perhaps it may be the original hub. I found a mention on a wheelemn thread of a 1900 Crescent catalog that offered a coaster brake option for $5. I have not seen the catalog so I can't 100% confirm. Is is possible that this particular ND hub is the correct hub when this bike was new?
