Master Model of Poland produces small brass parts for detailing models, be they aircraft or ships. They have parts for aircraft in 1/32, 1/35, 1/48, 1/72, and 1/144, mostly pitot tubes, refueling probes and gun barrels.
These are 4 20mm gun barrels for Japanese WW2 fighters. I had a 1/144 Platz N1K2 “George” on the shelf, which I built for a review about 4 years ago. I selected it for the upgrade.
Removal and Replacement
Removal was a simple job. I used sprue cutters and cut the guns off the wing, as close as I could to the leading edge. The kit has fairings at the base of each gun, but I fixed that later. Once I got the plastic guns removed, I used a sanding stick to flatten the base of the kit fairings. This gave me a clean surface to drill into. The instructions call for a .4mm drill. Looking at my .4mm drill and the guns, I downgraded the drill to a .25mm. The hole was still just a little large, but .25mm is about the smallest drill I’ve got.
