 Again: Welcome to Wikipedia! Your contribution was very interesting and so, of course, was the picture! Has the third vehicle already been mentioned in some independent source, a newspaper or something similar? If so, there is no reason not to include this information in the article. As regards the picture, I suggest you upload it — or some other picture of the same subject — to Wikicommons! Provided of course the maker of the picture consents. 

 Greetings,
