I had a chance just now to look in Garratt's Encyclopedia, and so far, no luck.
There's no article for Star Models, as such, and unfortunately, in the articles on Shamus Wade and Nostalgia also do not mention that trade name. Tom, Wade did enlist the Scrubys to produce the models according to his designs, for the Nostalgia line.
No mention, either, in the article on the Scrubys' own line, which Tom mentioned, Blenheim.
Charbens & Co. were not related to Wade or the Scrubys, but was an off-shoot of Britain's (one of the founders was a former employee of Britain). They were founded around 1920, and closed up shop in 1968.
Now, all this means is that there's no mention that I can find (so far) in Garratt, but he published the book in 1981. My next source is O'Brien's "Collecting Toy Soldiers", and if Star Models is a relatively newer maker, that is, if they started in business after 1980, there may be references in O'Brien. The drawback to O'Brien is that he last published an updated edition before 2000, and so, even his book is dated now.
I have to run out now, though, so I won't be able to post back until tomorrow. I'll ask tonight at the meeting, if anyone knows of Star (Art Etchells may, and the name is familiar to me, but I can't place it off the top of my head).
Till tomorrow, prost mysteries!
