Sir Wolf,
My GDFB cervellier is very light and works well over arming coif and maile coif, I have not got a great helm big enough to fit over it yet but would like to get a well made Pembridge helm. We also use the secret under chaperone hats etc etc.
Sir James, I too have considered having a steel plate rivited to my scull under my scalp, but as I don't have enough hair, I feel the rivets may show and loot rather unsightly.... What would you suggest??
G.
