I'm looking to have a custom Zero 0.4 made, but donor lenses have been a problem. I took my pattern (a beat up 0.4) to the O Store today, but none of the lenses there were quite right. I tried Jawbreaker, Radar EV, and I believe an M Frame. One that might work is a Radar Range, but they didn't have any in store for me to check. The Radar Path was close, so I think that the Range would work. Does anyone know, or have the two lenses to compare? The 0.4 that I want to make is the original 0.4 from 1993. This one: Zero 0.4 not any of the later ones, Squared, Golf Squared, etc. Thanks!
