Love that first picture Unkie...Ive got it somewhere but cant find it...Their is another with a pace in a very similar setting running the same way through long grass. And yes The last Image is perfect!...And your right even more confirmation they ran side by side.... Id go so far as to say Model 4 nearing its completion or last of stock,the model 3 in full swing and the model 5 starting its run... aVery nice and close intersection of all 3! Excelllent and enough id say to make it all but conclusive.. thanks for the Images!. And btw check ya mail...lols you got a pressie..Hopefullly.
