Sounds like the Dakking order was for the AUX SEND pots in the Neve 80 Series and SSL 4k, 6k. Although the SSL part has an extra wiper for TR, and the assby. had a Schadow, I mean Cannon, Uh, I mean Tyco DPDT on the back. The V3 is two or three Claro stacks.

Check with a local Honeywell distributor, and see if they still offer custom pots made using the "Clarokit" family of elements. I had a batch of Neve center detent line trim pots for an 8078 made about 7 years ago, and they made a batch of 100 for about $20 per. I got enough for two consoles plus spares.
There must be a V series support group out there. Good luck. Try Westlake Studios. They are tops, and may have a solution.
