Polecat -- the real deal?

a long story but sitting on the car boot peeling an orange, the benefits of eating fruit, when this came loping down the road towards me -- by the time I got the camera out it had gone! it reappeared with a baby rabbit and ran off down the road -- 20 minutes later it ran past 6m away and where was the camera? in the car!  persistence paid off in the end -- from the limited gen on the internet this looks like a real Polecat rather than a Polecat Ferret but I am no expert --the black from the eyes extends to the nose, legs and feet black, no unusual marks in the back -- North Lincs -- Canon 1D4 and Canon 300 2.8 II
