USS Carp was built by the Electric Boat Company in Groton, Connecticut and commissioned in February 1945. The Carp was active off the coast of Japan during the latter stages of the war. She survived the war and was based on San Diego as flagship for Submarine Division 71. To extend her usefulness Carp was upgraded in February 1952. The changes are pretty obvious to anyone familiar with Submarines. Carp was typical of the Electric Boat fleet snorkel conversions with a new larger sail that bristled with periscopes and all kind of apparatus. She also had distinctive domes on the deck and lower bow. These changes allowed the Carp to remain active into the early 60's first holding the line and then training new submariners for the new classes of subs that were replacing the old WW2 conversions.

Many of you are familiar with Mario Grima. His Model Ship Gallery is full of all kinds of ship subjects. But one look will tell you that he prefers subs. In his quest to build more sub types, he has take the basic Revell Lionfish and Flasher kit and produced his own conversion set.

The sail is cast as one piece and is not bad as far as casting quality goes. The sides are not perfectly smooth, but rather have an "oil canned" appearance typical of the sail sides on the real subs. The surface detail is pretty good as well with large raised rivet heads all over. You will have to do a little touch up on the casting, but not too much. Click images

 Revell originally released these subs back in the 70's. The kit is supposed to represent a typical wartime Gato class sub. But it is not very accurate. So one of the things in the set is this bow replacement. It requires you to cut into the plastic kit and graft this section in. This is not an easy task, but if you are willing to do the work, the parts are here to help make it right.
The other parts include the new bow deck, and the domes. The casting on these items varies, some will need a little more cleanup than others. Some of the parts are cast on a resin wafer and will have to be separated with a little flat sanding. This is best achieved by taping a piece of sandpaper on a hard flat surface and gently sanding the part in a circular motion until you have sanded away the base. This is best done with wet sandpaper to control the resin dust.
This is truly a multimedia kit with a wide variety of parts made of all kinds of materials. Rather than recommending that the builder fabricate items from his spare parts box, Iron Bottom Sound provides them for you. I especially liked the way some of these parts were taped to the sheet with labels to identify them.
The instructions are three pages that show the various steps to grafting these parts onto the Revell kit. 
This EB Sail Set among others is available direct from Iron Bottom Sound on their website for $39.50. You can even order online and pay via Paypal.  I have seen earlier IBS sets, and this one is a great improvement over them. It still some problems, mostly with the casting of the small parts. But it provides you will a solid basis to build your own Electric Boat sub conversion. Mairo has done extensive research on this subject and other more evolved Guppy type conversions and offers the fruits of his research in a variety of conversion kits. So whether you want to go with a full conversion or just a sail, Iron Bottom Sound has something for you.
