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.
This product is a single pitot tube for a Revell 1/144 F-106. The instructions are quite simple. 1) Cut off the kit pitot. 2) Drill a hole for the brass part. 3) Install the brass part, using CA glue. 4) Paint the part.
This Master Model pitot was welcome because I had broken the pitot on my F-106, and replaced it with a piece cut from a straight pin. The replacement was too short and way too thick. The Master part fixes both of these shortcomings.
I was able to bypass part of the instructions because I pulled the pin replacement out with a pair of fine nosed pliers. This left a hole in the nose which was slightly larger than I needed to put the Master Model part in. I used gel-type CA, which also acted as a filler for the oversized hole.
The new pitot went in, the CA filled the extra diameter of the hole, and I managed to keep the new part pretty straight.
