Hi MF these are the wheels from a place just up the road from here so I can pick them up without any problems. I have only put them on an alloy base Powertorque to see how they look and they don't look too bad. Gives it a rugged look similar to the Big Bobs/Tornados. I haven't tried posting any pics since the new format, not sure if it works the same as they did before but here are the wheels.

Bit of a pain but fixable. I did consider boring the center out and fitting a Delrin bush but I'm interested to see how the existing wears because it looks very similar to the MTD wheels and they don't have bushes in them, they run straight on the wheel
