This was a motorised toy, but released as a model kit. With judicious use of plasticard and filler it can be a good representative of the P4. Just don't look at the bottom. There is no detail at all and there are several holes to be filled. It has, thank goodness, rubber tracks. They are stretched tight if you use the 2 securing holes. If you use the second only they fit well. Be careful when fitting the road wheel mounts. The centre 2 are too close together so a little thought/work is required to ensure the road wheels don't rub.
