Slowly building a mechanical E-6B collection. Thanks

I, too, collect mechanical flight computers. Wondering if you can offer any sourcing help. I’m hunting for this nifty Cessna 172 wiz wheel that was marketed in the mid-90s by a now-defunct company called Cavok Int’l. They’re similar to the plastic, overlapping wheel performance calculators still used by heavier aircraft operators today. Any ideas where I might come by one?? Attached are a couple of pics of a friend’s. Thanks!

I don’t, but if I find out I will not hesitate to share information. That’s actually a neat looking device!
