Oh, that marvelous piece of American technology, the 1.1-inch quadruple anti-aircraft gun. It ranks right up there with the Hupmobile as the cutting edge of US design and manufacturer. Yes the famed Chicago Piano is a perennial favorite of early war USN modelers. However, the fact is that this piece of ordnance could not be phased out immediately on all warships in favor of the far better 40mm Bofors guns. The 1.1-inch mounts were over-weight, overheated easily and were subject to frequent breakdowns. As Bofors mounts replaced this infamous design in 1942, only the highest value ships received the new guns. That usually meant carriers and battleships. Even the cruisers engaged in the night time knife fights around Guadalcanal had the 1.1-inch guns replaced by Bofors in penny pinching packets. Some USN cruisers in that slugging match had combinations of 1.1-inch guns and Bofors fitted at the end of 1942. It you were on a destroyer or something smaller, that had the heavy 1.1-inch mount, it was "Don't hold your breath!" on the question of replacing this lemon with the magnificent Bofors guns.
Modelers might have thought themselves in a similar, but different nexus. However, instead of looking to dump the guns, they have been searching for the 1.1-inch guns to mount on their 1:700 scale thoroughbreds. Yes, there have been 1:700 scale 1.1-inch mounts available. Some are in photo-etch with outstanding relief-etched detail, but many modelers don't have the patience to bend the brass to the correct angles. Plastic mounts are available but injected plastic guns cannot hope to have the fineness of brass or resin parts. There has been an excellent resin version available but it is hard to find. Now, Loose Cannon Models has risen from the crowd of companies to shout out proudly, "I am Spartacus!" This of course is the Loose Cannon code for "Yes, we have resin Chicago Pianos!" Loose Cannon set LCW002 includes five 1.1-inch quadruple AA mounts in resin. Each mount consists of two pieces, the gun assembly and the base mount. With these parts you can fit your early war ships with pride, knowing that although the Chicago Piano was still an abysmal piece of ordnance, you now have really cool looking versions for your ship's crew to fire fruitlessly at those Vals and Kates.
