I just finished replacing fine crosshairs in a 10X Fecker scope (very similar to a Unertl). It was a pain working with wire that thin and fragile but I got’er done. Rather than send the scope off & wait several weeks to a few months, I figured I’d replace the crosshairs myself & also save the expense. So I bought 0.0005” diameter tungsten crosshair wire from a guy on eBay.

BTW, don’t get any ideas that I’m willing to work on replacing crosshairs for others. But if you’d like to try it yourself, here’s the link to the eBay wire supplier. You get 3ft for $10.
