Captain Dobey wears a white tie/ascot/scarf type thing around his neck. It is unique to the character and has not been factory reproduced.
Both DM and CTVT have made brown shoes. Doc Mego's are a little bigger in appearance, and lighter in color. They are marked DM on the inside. Classic TV Toys version are closer in color, although a touch more red. They are more narrow and tend to look a little rough with occasional flashing evident. CTVT's are unmarked.
