One of the criticisms I've read about the 1/72 scale Airfix Spitfire Mk.22 is the cannons are not quite the right shape or length. Apart from this deficiency, the Airfix Spitfire is an excellent kit and a great value for your money.

If you want to improve this model's looks and accuracy, however, Quickboost has a remedy. Their replacement resin cannons are drop-ins for the original kit pieces. Based on photos I saw, they capture the shape and size of the real thing. The kit's outboard cannons are too short, both barrels seem too bulbous, and both have an out of scale extension on the tip. Also, the resin replacements have no seam lines to eliminate – a definite plus, since the kit parts have large sprue gates. Smoothing out these sprue attachment points presents the possibility of deforming the circular barrels. Overall, the Quickboost cannon barrels look more refined and in scale. Check out the photos to see what I mean.

The Bf-109E instrument panel is the second instrument panel released by Eduard, the first being the Bf-110 panel. The kit consists of eighty five plastic parts on two grey-colored sprues, one clear sprue, two photo etch frets (one colored), and one decal sheet.

The construction sequence starts off with the Revi C/12D gunsight. Let me tell you, this is a kit in itself. The build is pretty straightforward. You just have to pay attention to the instructions. I put one PE piece on upside down and had to remove it and reattach it.

This one falls in the "that's an odd duck" category. This was a Japanese attempt – and a successful one, at that – to create a truly amphibious tank. The IJN developed the Type 2 Ka-Mi tank for invading Pacific islands that did not have adequate port facilities to handle regular tanks. The tank had removable pontoons fore and aft for flotation and to avoid shipping any water; they added a trunk for the air intake and a tower over the commander's turret hatch. It could do around 10 km/hr in the water, being driven by two propellers at the rear, and had a range of 150 km. These were probably test results in a bay or on a lake. I could find no information on its performance on the open seas, so I'd take that range and speed with a grain of salt. The vehicle was never used operationally in its amphibious mode, serving mostly as a dug-in pillbox on various Pacific islands.
