Master Models is a company that makes turned-brass after-market parts, specifically pitot tubes, refueling probes, and antennas.
The first thing I would like to point out is how good the packaging and instruction sheet is. The packaging consists of a zip-lock type bag while the part is in a smaller bag, keeping it from moving all over or losing one of these small pieces. The instruction sheet is very clear and easy to understand, needing only 3 steps: 1) Cut off original part; 2) Drill a hole (0.5 mm) and (0.7 mm) for the 20mm cannons; 3) Glue in the new metal part with CA.
Just be very careful drilling the holes, especially in 1/72 scale.
When compared to the kit part there is no comparison. The kit pitot tube and guns look like little blobs of plastic, while the Master Model parts are complete works of art. Once you use a couple of these pieces, you will be completely spoiled, and will never want to use the kit pitot tubes or guns again.
I highly recommend this product if you want a really superior looking model. The only problem I have now is that I want to use their products on every one of my kits. Thanks to Master Models Poland, and IPMS USA for the chance to do this review.
