Peter,
On the most recent photos of Stuart's collection that I've seen on GMIC(June 09) he had 22 home service helmets on his shelves, not to mention another 100 assorted helmets and pieces of headgear -all in cracking condition, so far as I could see.
I had a couple of mine posted in this section, but they disappeared in last autumn's meltdown. The most unusual one I have is a KRRC 1881-1890 grey cloth with plate and furniture in blackened white metal. I also have a number of cavalry helmets.
