Really? How much you want for it?For years I was required by GOM to carry a E6B circular computer in my flightbag when I flew 121. I bought one and left it in the wrapper and put it in the side pocket and never touched it. It's somewhere in the closet in pristine new condition never touched.

I still have my metal (not cheap paper!) E6B that has its own pencil holder. And two plotters. One is an SP-7, sort of a half-sized version of the SP-4 in the photo. The other is a "Rapid Course," which was actually pretty cool. Two connected parallel clear rulers. You placed one on your course line and the other on a nearby VOR to read the radial and skip the true to magnetic calculation.in case anyone actually wants to buy

Kind of you, but not necessary.If I can find it I’ll give it to you.
You'd think a real Vulcan could do a Taylor series expansion in his head.That is a real, honest photo of 'Spock' using an E6B. Roddenberry was a combat pilot, and he put that in a show as a joke.
Edit; used in Mudd's Women episode as well.
What’s a “kneeboard”?I keep my metal E6B in my kneeboard. If I remember it's there, I generally set it to my ground speed and try to reference it once in a while to compare the time and distance calculation the GPS is displaying. But I don't usually remember it's there.
Joke? I thought Spock was calculating drift from galactic winds.That is a real, honest photo of 'Spock' using an E6B. Roddenberry was a combat pilot, and he put that in a show as a joke.

I don't think you understand the reference. Spock did not choose the prop. The prop was chosen by the producer, as sort of a 'Easter egg' for us pilots to find and chuckle over. He knew, in 1967 that most of the great unwashed non-aviators would see Spock using the prop(a simple metal device), and believe it had some galactic significance. While the pilots viewing would be spitting Pepsi out their nose, laughing so hard.Joke? I thought Spock was calculating drift from galactic winds.
It’s an E6B case.What’s a “kneeboard”?

I am not far away from buying one of those off of FB Marketplace or EBay.View attachment 150430
E6B is basically a circular slide rule with a specific group of functions. I started college with this, and made it through Trig.
I had a slide rule almost identical to the one posted above and was told by my high school instructor I couldn't use it. Had to use long math only. I soloed in 1965 at 16 and used a circular E6-B that I still have but tried to relearn how to use about 10 years ago (for our Mail Run) and failed, bought a standard slider type as pictured above. Here at KFEP, once a year, we have a contest called the Mail Run. We are given 3 destinations to fly to, take a picture to prove we were there and end up back at KFEP. You have tell the contest director before you leave, your time enroute, to the second, and the fuel used, to the 10th of a gallon, then go fly the course. But; with no electronics! Nothing other than a map, compass, and a stop watch, or 3 stop watches as some use. And no electronics to flight plan either. Again just the E6B, a sectional, and a plotter. And it is truly challenging and fun! Winds aloft become critical to determine before you launch but also must be checked once airborne of confirm and make changes needs on the fly! The time in the air is typically around 1.5hrs.
You have to call a live briefer... on a rotary phone.That sounds like a fun event. How do you obtain the winds aloft data without electronics?

Pay phone. In a booth if you are lucky. In the rain.You have to call a live briefer... on a rotary phone.

There’s a pay phone on the street near the Philadelphia Convention Center. Last time I checked it looked like it was still in working order.Okay, so I'm going along with the joke, now - believe it or not, there's a place that this is - the reality. You've never been there, so go fly in and verify. At E02 in S NM, it's a medium size mountain strip. There is NO cell service in the valley, and there is no aviation radio service except maybe, sometimes, if you are lucky you can reach Biggs AAF tower freq. If you do reach them, and they do talk to you - are you going to ask the tower to call FSS and relay a full pre-flight weather brief? Yeah - good luck with that. But!/however! A few paces away, around the corner, just over the Sacramento river bridge, in all it's glory is a PAY PHONE. Does it work?
I have literally schlepped over to the pay phone, dialed wxbrief and gotten my weather update. Since it's a mountain airport, things can be a bit exciting sometimes with the winds, and with the fog and clouds on the western side of the Sacramento range(good sailplane location). It's a hoot and a half. I had the runway paved a few years ago, but it's got plenty of weeds coming through because the jerk that manages it now is a clueless tool. Still a nice place to fly. Land 31 T/O 13 only. Up the street is a small deli, and there are bathrooms there, or the gen store further up the road. No services, no tie down, and don't try to break into the tractor shed, it's on 24 hour camera coverage.
You couldn't pay me enough to touch that wearing a yellow HAZMAT suit.There’s a pay phone on the street near the Philadelphia Convention Center. Last time I checked it looked like it was still in working order.
