These darts were given to me by a lady whose dart aficionado husband passed away. I am happy to honor his memory with a Ton-80.
Another back-blogged maximum. I don't remember where I was when I hit this. I want to say I was at home because those are clearly FitFlight stems and I do not think these darts were given to me with that system. It would be unusual for an old timer darter (especially one who passed away) to just happen to have dressed his darts in my (then) favorite modern stemming-flighting system.
These darts came to me in a blue, snapping, folding case that said "P.E.N. Darts Netherlands Range" or something to that effect. I do not know for sure what they are but I may try to track them down at some point.
