Are you familiar with Japanese Puzzle boxes, sometimes called “trick boxes” or “secret boxes”? A Puzzle box is a box that can only be opened through some “obscure or complicated series of manipulations”. The boxes contain a good luck charm and are designed to trick or confuse the person attempting to open them. Some require only a handful of movements in order to slide the various parts of the box into an “open” configuration, and some require hundreds of manipulations. Indeed, Japanese Puzzle Boxes are known for their complex and challenging design but they are also known for their intricate geometric patterns and their exquisite engineering and construction.

Delta One has been producing some unique decals, especially for the Bf-109. So that means that I had to check them out. This particular sheet covers the Yugoslav Air Force Bf-109s in service from 1945-53.

This sheet comes in a ziplock baggie that contains an eight page booklet with history and line drawings for the subject aircraft. There is a little history on the 109 in Yugoslavia. There is also a brief description of each aircraft including the colors and historical use.

Decals are provided for six aircraft, four G-6 aircraft and two UMe-109, which is a version of the G-12. The profiles have both side views, top view and a partial bottom view. The aircraft are interesting with some unique paint schemes. The actual decals are on 3 x 3 inch sheet. They are printed in perfect register, thin and with good color saturation.

The Heller Mirage IV is a slightly older kit, but still the only option in town. The Mirage IV has its refueling boom off of the nose so it sits out there just waiting to be knocked off or bent. Enter Master from Poland.

Why do would you want to use the Master turned metal part? Well there are numerous reasons. The first, and most important, is that turned metal is stronger. Another reason is that you don’t have to worry about the mold line or keeping the round cross section all the time worried about losing detail. These reasons are enough for me to use the metal parts.

Packaged in a Ziploc bag, this set is a single piece of machined aluminum. The refueling boom is perfectly rendered and captures the shape of the tube and probe. This set is simply a replacement of the kit boom. You may not even have to drill the hole unless you accidentally filled it with slurry of plastic while gluing the nose.
