In addition to hunting sprigs seen on several more standard sized Thomas Smith jugs, this has an unusual sprig of a Chinese musician. A similar sprig has been seen on shaving mugs from my Unidentified Maker 1 (see link from Home Page).
 

The impressed inscription on the front of the jug reads:
HERE'S TO THE (sic) MINE HONEST FRIEND
HOPING THOSE HARD TIMES TO MEND
J. D
