Thnks for the comments guys..
Andrew, the road wheels were airbrushed and then the rubber portion was hand painted..

Took just over an hour to do the lot...
Biggles.. No, I havent forgotten the commanders coupola..Its just sitting off to the side waiting to be finished.. The barrel may have rotated somewhat.. As you are aware, this has a recoil set up on it.. This allows the barrel to float a bit.. Thanks for picking that out.. I didnt even notice it..
