Nice set George.
I was at Donington, but despite the lack of spectators I wasn't allowed out of the paddock/pits area & wasn't allowed to wander into other parts of the paddock...
The view from my pit garage was very limited, and there wasn't even anywhere I could get a coffee!
Probably would have been a good chance to catch up on some post processing. Maybe next time!

I would expect it to be rather hard to track down an original unit, but it should be easy to get a generic power supply of the right output & modify it.

It looks very much like the Beike BK-45 I got a week or so ago (for £27). Though the Beike does have an extra bubble level.
Looks good at first glance, but drag on the vertical swing tightens/loosens as it swings. The manual only covers it's use for panoramas (suggesting that's it's main function).
My only testing so far has been in the dark on a travel tripod where vibration made it quite useless for my 1000mm lens - which also wouldn't balance right on a 4" aria plate, somewhere I have a longer plate.
Hopefully I'll get the chance to try it with some other combinations.

I like the idea of a book swop box I seem to recall something of a national movement for this, there is one in the local railway station for instance.

Yes freshly made paper & printing ink is likely to be sterile (paper is typically bleached & printing inks contain loads of nasty chemicals) but I don't see this produces any protection from surface contamination later in it's life.
The risk certainly isn't high & and will go away after a few days, so it's not something I'd worry about. Using baskets/trollys at the super market is a much greater risk IMO.

lens alone would not be enough to convince me to switch from Pentax, ( I know because I already switched from Pentax to Sony) .
Simply put... Pentax lenses generally are superb and usually value priced in their respective classes.
for example...
My WR DA 100mm macro.... I have an adapter with aperture control to use this lens on my Sony A7III. Why?
Two reasons:
a) in different macro lens shootouts the Pentax bested the 90mm Tamron and the Sony 90mm may be the highest rated macro on any system.. BUT it's not a huge jump ahead of the Tamron, meaning it's not edging the Pentax out by much...
b) I can live with manual focus for portraits and macro shooting, so whatever.... SONY 90mmm macro $1400.00 CDN, Pentax 100mm macro $649.00 CDN, Tamron 90 mm macro $949.00 CDN as of this writing...
Who cares if there's more options, with other brands when there's really only a few sensible choices?
having fewer choices isn't reason enough to switch, if the choices you have are generally excellent...
Pentax not offering pro video specs in ANY camera body..... THAT WAS REASON TO SWITCH!
Nearly all my Pentax lenses can be used with AF on my A7ii. Including many that are manual lenses. My Takumar 300/4 is one of those too heavy for adapting that way. The Auto 110 lenses don't support AF either but they can be used if you're happy to ignore the poorer coverage they work manually (unlike on a PK body).lens alone would not be enough to convince me to switch from Pentax, ( I know because I already switched from Pentax to Sony) .

My K5ii rarely gets used but it does come out for the local airshow. It typically shoots 3000 images a day during the airshow!Wayne, just to let you know your original K-5 ii is still in active use, and is also at the 3,000 mark now

My own efforts have never come out anywhere near a good

The point is it might be the cheaper option as well as working much better. Even if you use an adapter to use your existing Pentax glass...Whatever the benefits of an IR mirrorless camera, it misses the point somewhat.

Like Barrie I went for a mirrorless model when I got a converted body. My initial one was brought pre-converted for less than the cost of a conversion.
More recently I've brought a FF body & had that converted by Alan Burch on the isle of wight. I should be able to shoot UV as well as IR with the new one, and can fit a clip in filter to return the camera to normal operation too.
I've come across a useful comparison of conversion companies on-line, giving contact details etc for each.
