Yes…yes he did. 
Good one EricK! Chuck Norris shaves by roundhouse kicking himself in the face because only Chuck Norris can cut Chuck Norris. 
Which one of you is the psychiatric nurse?
That would be me…but isn’t it obvious why I’m the perfect man for the job? Or is there a reference to ColorForm I’m not getting? Perhaps we’re all crazy by association. That’s also possible.
LMAO!!! You guys are killing me!!
Oh yeah I don’t how I could have missed those
Im not a nurse just a patient 
Does anyone helped the guy that started the post?
As for the first writer, would an minimoog service manual help?

I believe this was the answer to the first poster’s question, space_nerd. Now…back to your regular scheduled program…
Chuck Norris broke down and confessed that the original part # is:
Allen-Bradley JA1N200P505RA
This is a “clockwise modified log” taper.

It’s a reverse log taper?
Where did you obtain that number? 
Early Minis did use an AB pot in that location.
But later ones used an open type.
So…
505 is a 5 meg.
UA would be linear.
AA would be audio.
RA would be modified taper?
I think BA is reverse audio.
The thing is that AB offered several LOG tapers.
10%, 20%, custom, etc.
What a “modified” taper is, I’m not sure.
The glide pot rarely fails, so I can’t recall if I’ve ever had to replace one.
A linear might do if desperate.
If yours is a very early one with an AB pot there, finding an original might be very difficult.
In all seriousness, I have an Allen Bradley pot. It cost me eight bucks. I didn’t understand until now WHY it was eight bucks. It won’t do you any good as 1) it’s 100k and 2) I need it for Kevin’s color changing wheel circuit. However, get in touch with Chester Electronics in Kenosha WI. and see if they have what you need. They have almost everything!

It turned out this was the only pot that hadn’t been changed; I got the A-B part # off the back. I was able to locate an old A-B catalog and look it up.
JA is the basic type
1 is the lug location
N is the bushing type
200 is the shaft length (2")
P is the shaft type (Plain round)
505 is 5 meg
R is the taper. It is clockwise modified log (A), 20%. NOT reverse log.
The A-B catalog shows a plot of resistance versus rotation for the various tapers and I was able to verify with an ohm meter. The modified log has 50% resistance at 70% rotation. Regular log (DB) has 50% resistance at 85% rotation.
A is the hardware (nut + lockwasher) combination.
DigiKey has a large selection of pots made by Precision Electronic Components Ltd which are very similar to the Allen-Bradley ones (which are no longer made).

Cool it was an audio taper.
I feel vindicated.
Please note that while Digikey carries the PEC line of pots, these pots will not work well for replacement of the mod wheel pot.
The PEC’s “end resistance” is not low enough to shunt the modulation out.
Fine for the glide location though.
I tend to use Clarostats myself, but even they don’t work well for mod wheels.
I just like them better than PECs overall.
Your mileage may vary.
Best of luck.
