Trim is 1959 - 63T on the Body plate if that helps. Def two colours going on there, three if you include the dark brown carpet...

It's not Oyster is it?

Getting back to the original question in this thread, I would suggest that the factory's choice of steering wheel has everything to do with the column-mounted shift lever ... I'm referring here to the relationship of a driver's left hand, both to the wheel and the shift lever.

Ideally for a column shift configuration, the steering wheel should be rigid and circular, neither of which is a characteristic of the standard Statesman single-spoke item. Also, the rim of the wheel should be positioned comfortably to the end of the shift arm.

It's a while since I've driven a column auto of any kind, but my habit of old was to hook my thumb on the wheel rim to operate the shift lever.

The reason WB changed is because Commodore and Calais changed over the WB series model run from early 1980 through to early 1985. During this time VC became VH became VK. No different to later Holden ute, it changed trim with Commodore/Calais. Just look at VS Holden ute, once VS passenger vehicles ceased and VT and VX appeared VS Holden ute changed trim accordingly. Even in earlier series, at or soon after LX Torana release HJ trim all changed across the range not just in commercials. Even HK changed when HB Torana changed, and vice versa, at the HQ-HJ series interface LH Torana trim all changed from HQ to HJ trim.

I do like the comment about the steering wheel & relationship to the column shift. Being that an '84 WB Sedan was using VK commodore interior colours, it would make sense to use a Commodore steering wheel in the same colour, rather than a commercial wheel. Normally the WB sedan would have the single-spoke wheel, shared with the SL/E or Calais at the time, just with a different horn pad & badge.

But I think the comments above about the 2-spoke wheel from the low/mid level Commodore are quite valid - the flex on the single spoke is quote pronounced around the top third of the wheel (say from 10-2) in a forward-back direction, but less so in a rotation direction. Knowing that both those wheels place the rim the same distance from the driver, it rules out the wheel rim being too close, or too far away from the shift lever. So flex when using the wheel to brace the hand when moving the column shift lever could well be one point considered.

The other aspect could be safety for the lowest common denominator - there could be temptation to put your hand through the steering wheel and on to the column shift, rather than around the wheel. The 2 spoke wheel doesn't leave enough vacant real estate to really do this without being a bit of a contortionist, so perhaps that was also the thinking as well.

Perhaps there was also the thought of offering a very basic WB sedan as well? 6-seat, column shift, and no power steering maybe? The single spoke wheel is only allowed to be used on cars with power steering (quote obvious from the flexing issue) so the 2-spoke, also used on non-power steered commodores, would be the natural choice for that too. It may not have ever gone into production in basic form with no power steering, but the spec level for a column auto could have been built up from there.

What were the last of the WB Commercials using for a steering wheel? Were they all the 3-spoke sports style wheel? Or a Commodore 2-spoke wheel?

Late wb commercials had older hz wheel but in new colours
Also had sports option gts type in same colours, seen this in odd statesman too, maybe single spoke wheel just for caprice.
Several items saved for it as it was a fair bit more expensive

How or who can repaint steering wheel?
No one seem to have had much sucess

AFAIK that isn't a WB Kingswood sedan. It is the prototype WA Kingswood sedan. Have you seen under the bonnet? I tried last time I was there but the curator was offsite. Would like to see what ID is on it. I'm pretty sure it would be a HJ body not a HZ. Note that this vehicle is essentially what came here (but in HQ guise) as GMH's new HQ Holden sedan when they were sent here by GM to replace GMH's proposed HQ (which was a heavily facelifted HK/HT). GMH designed their own sedan based upon the SWB coupe and made the sedan into the Statesman. From what I understand the HQ was supposed to be replaced with the HV around late 1972 and the WA replace the HV in 1974. I always thought that car was the WA sedan design from around 1971-2.

There was never a WB passenger line. WB grew out of the cancelled WA series, it simply used WA front styling.

Yep, Oyster it is. Finally dug out the WB parts manual and that's what 63T is.

Also saw a WB Series II Statesman brochure on eBay where the seller kindly took good pics of each page and the bench is listed as an option, but available with Oyster interior only. Explains why the 2 other bench-seat WB Statos I've seen on the web were also Oyster.

Wondering why there was never a WB commercials Series II. Probably they were selling well enough that Holden didn't need to spruce them up with a SII version.
