I'm no expert on the
Monitor, but I did do a considerable amount of reading about her some years ago when I got commissioned by the
Monitor Marine Sanctuary and the Mariners' Museum to design a paper model of her. Though I haven't looked at the Verlinden kit, on the basis of the photos it looks to me like the designer did a fine job.
The big difference between the kit and the ship's appearance during her fight with the
Virginia seems to be the configuration of the pilothouse, the big box on the foredeck. During the battle a Confederate shell hit the pilothouse, damaging it severely and temporarily blinding the ship's commanding officer. The Verlinden kit appears to represent the replacement pilothouse, with its sloping sides. It looks to me like it would be fairly simple to slice the slanted parts off, leaving the original, boxlike configuration. The edges of some plates would have to be scribed, but that's fairly easy with resin.
The other box-like structures projecting from the Verlinden kit's deck are the intakes and exhausts for the engines. They were part of the original design, and presumably were in place when the
Monitor made her initial voyage from New York to Hampton Roads. When the ship cleared for action they were removed, so they wouldn't interfere with the fields of fire of the guns. Also as part of that process, the ventilation ports for the officers' cabins and other below decks spaces (which show up as round, black dots on the photo of the Verlinden kit) were closed with sheet iron covers, and the turret was jacked up a few inches. (During open water voyages it was lowered to make a watertight seal around its edge. That idea, it seems, didn't work. It probably was water leaking in around the circumference of the turret that sank the ship.)
One other interesting thing about the Verlinden kit (speaking, again, solely on the basis of photos on the Squadron website). It looks it provides two optional tops for the turret - one solid, one an open grating. Good idea. I've lost track of the most recent research, but when I was reading up on the subject nobody was quite sure how the top of the turret was built. Ericsson's original drawings left room for doubt, and none of the old photos of the ship was taken from a high enough angle to answer the question. (In at least one of the pictures men are standing on top of the turret - so there must have been something for them to stand on, but it could have been either a plated deck or a grating.) When the ship sank the turret fell off, landing upside down under one edge of the inverted hull. Until recently even the divers, though they could touch the turret and swim partly around it, couldn't tell what the top of it looked like.
A year or two ago the turret was brought up and taken to the Mariners' Museum. I haven't seen it, but I did have a talk with Brad Rodgers, a nautical archaeologist and conservator, who got a good, close look at it shortly after it was raised. He said there was so much concreted crud around the top of the turret that he couldn't tell whether it was originally open or not.
A few weeks ago the turret got put on public exhibition for the first time; I gather that means the conservators have made significant progress on it. Maybe it's possible now to tell which - if either - of the Verlinden parts is right. If I had to put money on the subject I'd probably bet on the grating - but with a considerably finer "grid" than Verlinden seems to depict.
The Verlinden
Virginia kit inevitably is based on a good deal of guesswork. There are no known photos of the
Virginia, and the only contemporary drawings of her are extremely sketchy. To my eye, though, the photos of the Verlinden kit look thoroughly believable.
The biggest question I have about it is the color scheme. The model in the photos looks like it's painted light grey. That's not inconceivable. I recently did some work with another Confederate ironclad, the C.S.S.
Neuse, though. The folks in charge of her - who are extremely knowledgeable - are fairly firmly convinced that Confedeate ironclads in general were treated with the same chemical that was used to protect cannon barrels. It was a mixture of paint, tar, and probably some other stuff, concocted to stick firmly to iron and keep it from rusting. If it wasn't pure black, it was pretty close to it.
I would, however, be extremely reluctant to make any generalizations about the color schemes of Confederate ships. There were no regulations or standards for such things, the documentation is extremely sketchy - and the
Virginia, having been "built" under such freakish circumstances, may well not have adhered to any standards that did exist.
