1. In regard to pagri not referenced in Litchfield's book, do they bring higher prices?

Not necessarily.

2. Most of the pagri I see on dealers websites sell. Some faster than others. Are there that many Royal Artillery collectors?

Yes

3. How about the value of embroidered (bullion and non bullion) pagri?

Bullion harder to find, ie - RHA

4. How much value does a pagri add to a sun helmet, slouch hat or MK II helmet?

The value of the badge

5. While the plain red and blue diamond is somewhat common on MK II helmets; I have only seen one with a unit specific pagri. I presume such headgear sells fast.

No idea
