The focusing rack is worth £40 alone.
The P stands for portable.
The missing item is probably a camera? The only other thing could
be a table clamp, but the cutout looks more like a camera.
Well worth buying.

Is it possible to add these extension rings to a macro lens to get even closer? or should they only be used with standard fixed lenses?
Another question the set contain 3 extension rings (13, 21 & 31) is each one for a set lens or magnification?
with lenses smaller than about 20mm because the subject becomes too close to the lens.
The magnification depends on how close the original lens can focus.
The sizes are probably arranged so that 21+31 = 52mm = 2 inches
The 13mm is half an inch.
52mm + 50mm lens should give about 1:1
There's loads of stuff on the web and probably videos on Youtube.
This threads quite good for calcs: link

Hi all, a response this evening to a query I placed on Pentax UK Facebook page...
Will Pentax be at 'Focus on Imaging' at the NEC this March please?

Pentax UK Hi Bill
We can confirm PENTAX will not be taking part in the Focus on Imaging 2012 show in Birmingham.
However, we will have some exciting and significant announcements to make in the months to come and we will be attending the Focus show again in 2013.
PENTAX
Sounds like something new in 2013
