I too, am interested in this model train company. I have another Unique Art item and was about to list it on eBay for $.99 plus shipping, hoping to find it a new home where someone may know something about it and want it.
I am 56 and when I was a kid during the 50's my Dad and I set up our wonderful Lionel 027 trains every Christmas. From somewhere, there came a matched pair of large O gauge Rock Island Rocket diesels. Lithographed tin with pressed steel trucks. Big 'ol light bulb headlights. They were large and loud and would not track on the 027 track - derailed at the first curve. They were always left behind from the rest of the Christmas trains, left in their box.
Now, 50 some years later, I would love to find something about them and perhaps find them a good home. They are _big_ 4 X 14 inches with slot and pin couplers. They are in their original box, without any original insert packing. And they have some corrosion spots here and there.
They are pretty neat, and the box is lettered:
ROCK ISLAND DIESEL (DOUBLE ELECTRIC ENGINE) UNIQUE ART MFG. CO., INC. NEWARK 8, N.J., U.S.A.
Thanks!
