The Westminster Abbey arrow was found in the roof of Henry V's Chantry in the 1870s and has been tentatively dated to the 1430s.  The arrow features a subtly barrelled shaft, deep red fletching compound and goose or swan fletchings.  The head is a delicate Type 16 with tucked-in barbs.

This is a faithful replica of the original, with all dimensions and details carefully followed.
