The kit almost has to be the ITC (Ideal Toy Corporation) U.S.S.
Oregon, from the fifties or sixties.
It was re-released not terribly long ago (in a slightly revised format) by a company called Glencoe Models, which specializes in reviving old kits. I'm not sure whether Glencoe is still producing it or not, but it probably can be found in hobby shops.
The original, ITC issue, if I remember correctly, was molded in several colors; the Glencoe version is all grey. It wasn't a bad kit - for its day. But it really shows its age. In its original incarnation it had an electric motor, the batteries for which took up considerable space inside the hull. As a result, ITC made some major concessions in the way of accuracy. As I remember, the central section of the boat deck, which should be one level lower than the catwalks running around it, is in fact flush with them. The Glencoe re-issue doesn't include the motorizing gear, but Glencoe didn't fix the deck.
I believe
Fine Scale Modeler ran an article some years back about how to make the Glencoe kit into a reasonably accurate model of the
Oregon's sister ship, the
Massachusetts. That modeler, if memory serves, corrected the problem with the boat deck - among many other things.
Gold Medal Models makes a set of photo-etched metal detail parts for this kit. (I believe the set also contains parts for the old Revell U.S.S.
Olympia.) I haven't seen this set, but on the basis of experience with other Gold Medal products I suspect the instructions give lots of suggestions on how to make the kit more accurate. An easy way to get to the Gold Medal webpage is through the Steel Navy website, www.steelnavy.com .
Unfortunately the
Oregon and the
Maine bore little resemblance to each other. There has, to my knowledge, been only one plastic kit with the name "Maine" on it. It was made by Pyro back in the fifties, and was in fact a reboxing of that company's U.S.S.
Olympia kit. The actual
Olympia bore even less resemblance to the
Maine than the
Oregon did. This particular little scam has long been pointed to as one of the worst examples of false advertising in the plastic kit industry. Unfortunately that Pyro "Maine" has also been through some reboxings - including, if I remember right, one by the French company Heller (of all people).
The only really decent plastic kit representing a warship of the Spanish-American War is generally conceded to be the Revell U.S.S.
Olympia - a completely different product from the crude Pyro one. Unfortunately the Revell kit is hard to come by these days.
The wood kit manufacturer Bluejacket ( www.bluejacketinc.com ) has just announced a new, state-of-the-art U.S.S.
Maine. The bad news is the price: something in the neighborhood of $600.00.
Sorry to be unable to bear gladder tidings. Hope this answers some questions - but take my senile memory with a grain of salt.
