GeeCee

I believe it's the serial number having seen several over the years with a P. and always a different number on the plate (and the left-handed version had LH after the digits). Highest number I recall was P.019.

Do you remember who did the woodwork on the Chieftains? Was it Shergold Woodcrafts by any chance?

That was Scojack's website.

If I remember correctly, that's the first Warlord bass on the right.

Welcome and very nice bass. Why the two jack inputs?

Slipping out of the groove in the roller saddle on the Schaller bridge when slapping due to the low break angle, I believe. Mark King said something similar and that is part of the reason why he ditched his pair. The owner was and may still be a member. I don't recall his username, but if you do a search for Pangborn, you can read it in his own words. You will have to go back a ways but there is not that much Pangborn content. What you say is true, though the late John Diggins always maintained that the initial similarity was more of a happy accident and based in large part on a customer's design specifications, which was an attempt to copy an Alembic. He would also say that Ashley Pangborn spent a fair bit of time studying his instruments at trade shows over the years and you can see them evolve closer to a JD, for example, in terms of the control layout. That said, Pangborn's instruments were (mostly) neck throughs, while JD stuck with the set neck design.

Because that is a JD roller nut by the looks of it (helps with string bending). The bridge and tailpieces are also JD pieces, as is the brass PU selector surround. I think this bass had a Schaller 3D bridge originally and the owner had problems with the strings slipping due to the shallow break angle and took it to Jaydee to be "fixed". And, let's face it, Pangborn was always heavily influenced by JD (funk groove was another JD signature, not Pangborn).

Here is a fancy series IV Jaydee:

It's genuine, I know the guy who had it made (for his daughter, I believe). There are half-a dozen short scale JDs out there. This is one of the more plain ones. It's a Roadie II, passive and was originally cherry red. The short scale design is referred to as a series IV. PS. Roadies are part of the Supernatural range of basses too.

The latter I believe. I vaguely recall that is a MK model under the paint, which, if true, would be an odd choice really, better to have started with a Roadie.

Seconded, JD does use some nice hard-wearing ebony for their fingerboards; just curious do you know what body the neck was originally attached to?

Sounds right

You can but ask, though John is essentially retired, so it would be up to Mike and Andy as they would likely be the ones that would have to make it. Hard to say, they don't do as much non-Jaydee work now and the model choices have narrowed somewhat. Pretty easy to replicate though, 62 jazz copy, no scratch plate, plain ebony fingerboard, active EMG pick-ups (battery on back), and black hardware throughout (machine heads, control plate, bridge, etc.) Would look like this:

Not normally, no, Roadies do have a central strip of maple. In this case, the maple strip is painted over to look like ebony. Anorak fact, the first couple of Roadies made actually do have a central strip of ebony instead of maple.

Different basses I think, look at the figuring on the upper bout in the above to the fretless. There have been a number of Roadies redone in recent years.
