Robin Hood - part two

Following on from yesterday's blip, here is the second of three fine bronze statues at the outer wall of Nottingham Castle.
There is no descriptive plaque to help identify the characters, but clearly Robin Hood, knife in hand, is the central figure, resting back-to-back, and apparently exhausted, against a rather reflective Friar Tuck.
The identity of the third character is a matter of speculation, but my guess would be Will Scarlet.
Any other opinions or information welcomed.
