These little beauties are a sheer joy to throw. They are light as a feather, or at least feel so. I can only assume that they were made by someone, somewhere as a soft tip dart. They are all brass with an incorporated stem, and only a small stem top to hold the flight in place. The sleekness of the body and the thoughtfully engineered flight holder make me think this was a professionally done dart. They are slightly reminiscent of a Bottelsen GT.
The body is all brass, and the flight holder is a small screw-in piece that looks like it could be the top of an old two-piece stem, but I have no idea what thread it is. one of these days I am going to get a tap and die kit that will allow me to determine exactly what the various threads are on some of the old darts I have, including this one.
The Reflex conversion points fit them like a glove. They almost seem designed with these darts in mind.
Throwing them takes practice. Once you get the hang of them they fly pretty well though. Chucking them at the triple 20 will reward you with ample 1's and 5's because they are so light they are kind of like chucking a feather at the dartboard, but I eventually got on with them well enough. In a round of doubles practice last night I hit a Doubles Trick in the 18, 19, and 20 as you can see below.
