Ended up going with this stand. Had a look at a mannequin type head I had and how high it is and think this one will be plenty high to get the helmet off of the ground so to peak. Once I get the helmet I'll post some better pictures in latest finds.
I have been out of town for the past week, but I hope I will still be of some help. My spiked helmets range from 10-12 in including spike and my artillery is about 10 in including ball. Great looking helmet by the way!
