Found it. The larger skin. Not much use though as it has been out in the rain, sun, frost etc for too long. It is about half a kilometre away from the house in a vine row in the high cover crop.

Either Siegfried carried it there and he well may have, as he runs up there many times a day to check on the local rabbit population, or a fox found it and dragged it there.

The little bugger.

The meat from the two deer filled approximately two and a half eskies (cold boxes). Fitted in the gaps of my large freezer so I still have the smaller one to fill.
