Fantastic! I made one of them too back in the day! I did not have any Ork models so my brother used it in games, but it was great to have a go at a relatively simple scratch build and for GW to provide rules for it.
Your Gobsmasha's Pritt Stick cannon might have outgunned my vehicle's Smarties Tube main armament, but my tank was definitely faster - it was painted Evil Sunz red like the one in White Dwarf!
