The "leg" in the lower left of the bag is actually some sort of strap buckle.
Roe deer get bigger west to east. Smallest are in Western Europe and the biggest are in Siberia. (Likewise with Red Deer and Wild Boar.)
The smallest deer I ever shot (with a M-S Model 1903 6.5x54 fullstock carbine) was a Texada Island Blacktail...also probably the most tender.
Like shooting dik dik in Africa. - dan
