Cleaned out the garage last weekend and I have some leftover parts from my English Mark Darts machine that I upgraded to the double bull. Since the single bull uses a different target interface board and dart head segments, I no longer need these. I do have them listed on eBay if you feel more comfortable buying from there, so here are the listings:
Segments Target Interface Board $10 discount on the segments and $5 discount on the interface board for members buying direct from me here - I can do Paypal.
I also have two complete dart head assemblies with all the segments, the spider, backing board and matrix however both matrixes have issues - some segments don't register. (tried various "untested" options from eBay over the years) Let me know if you're interested in one or both and we can discuss a price.
