Defiant tail wheel

I wondered if anyone could help identify whether this is a Defiant tail wheel, there are no markings on the hubs but the tyres have the following markings4.95 – 3 1/2 Electrically Conducting 92-L0570 5 014/2 WM14 31234 31233 &4.95 -3 1/2 Electrically Conducting 113G9974 5014-2 WM14 30790 30789. Here are a couple of pictures.
