WTB: PWD Mk2 upgrade kit?

I just bought an mk1 pwd and naturally I’m looking to upgrade. I can’t seem to find the going rate of anyone who wants to sell their mk2 parts. Is it worth it?

They originally sold for $795 for early purchasers and (I think) $995 later. I thought it was a tremendous improvement over the Mark I. Be aware that there were four different versions of the kit to fit different configurations of the PWD. The different versions fit different back panel arrangements on the various vintages of PWDs. I can no longer find the guide to determine which version to select. Mine is number 4.

Here’s the upgrade manual.

i have one downstairs. Let me know if you want it.
