The USPTO tells us that RDs and REs are issued in the same numeric
sequence, so the RDs are scattered about. From the USPTO's Patent
Number search screen you may search RDnn$. Searching nn= 20 - 30 one at
a time I found the hits shown below. RD301 from the year 1855 is a
lovely metal casket with a window to permit viewing the face of the
dearly departed. RD21452 is a cactus-type lamp from 1940. The others
are more mundane. Of course you must install their image viewer to see
the designs or front pages.
