re: A Wee Beastie in the Printing
Nice item, but isn't a circular spot like that caused by a speck od dirt on
the plate and while several examples may be printed it eventually is rubbed away, which makes it (If I am correct. ) an EFO rather than a printing flaw ?

I think of these as a bubble of ink on the plate. As the top of the bubble touches the paper it creates a channel for ink around the bubble to soak into the paper, leaving a circle where the ink has been wicked away. Just my 2 cents.
Gents it's a foreign body that got in-between the plate and ink and would disappear after a few had been run off sadly it's the sort of event that would never be picked up by quality control on automated presses.

Just a matter of money. COTS automated inspection systems can detect sub-micron (very sub-micron) defects, but stamp defects aren't worth that kind of money.
Q/ When was the last time you bought a book with an inking defect?

Yes and no, Ike.
Temporary freaks are sometimes interesting attention getters, and generally of no particular value.
But defects, such as the left band ½p, or the missing "£" on the £2,oo issue fetch a significant premium.

That fault is far more impressive than the regular "ring-flaw" of dirt on the plate which usually requires close examination to see it.
I am sure that there would be a few Machin specialist who would want it in their collection.After all there are so few errors in modern printing these days -the quality control now is awesome.

Permit me to clarify:
"... but stamp defects aren't worth that kind of money to the printer, eg, so as to be worth the investment to catch them in the first place ..."
Hope that helps,
