Encoraged by this thread, I've been doing some searching through my books and found this very interesting comparison between early-model Tiger wheel ( on left ) and late-model ( on right )..
Note the smaller-diameter appearance of the later-type steel wheel. Now - here's the model...
So - I think I may have been too hard on FOV earlier - if you compare these photos, the model actually looks pretty good for a late-model Tiger. I stil lthink that the track sags just a little too much - but it's not as bad as I first thought.
Overall, it's still one heck of a model - and now, I feel even more pleased with it !
