Hello,
Currently on ebay are two photos of a Curtiss JN-4D(?) serial 212* at:

To be honest I'm not totally sure of the type of aircraft shown. Checking Joe Baugher's site at
http://joebaugher.com/usaf_serials/1908-1920.html which I usually do leaves me no clearer as 212 was a Sturtevant S-4 and all machines in the 212* range appear to have been cancelled.
Regards,
Clint
