Ron, not sure, really. It feels like it was shiny before rust and neglect set in. I have taken off the mount for the spike on top and the shell was shiny underneath, yet again i don't know the process of how it was made.
ANYWAYS, used a mixture about 40/60 stripper and water with a scrubber pad for the paint, rinsed with plain water and dried thoroughly. did this to the inside front, rear and center and outside entire shell, after having taken off the spike mount and wappen.
Took it inside (Fingers still frozen) and gave it a second round of spraying with a commercial ready-strip rust remover (with a new scrub pad) then rinsed and dried thoroughly again. After this with a cotton lintfree cloth applied a gum-free gun oil to all metal parts and reassembled the spike mount (screwed-bolt, washer and nut in original order of course) and then fixed the wappen to the outer face of the shell with real leather cord (same way my other pickelhaube is)
I may go on another wash, maybe 10/90 stripper/water to 'finish' the paint around the rear bolts. (If I could remove those bolts it would be easier to not affect more area than needed with the stripper ((which really takes a toll on the finish)))
All things considered it was a learning experience, thankfully the shell wasn't one of those 1000+ dollar experiments (those are awful, especially waking up the next day "what did i do?!")
So if you see a painted-by-gradeschool-teacher helm, don't be too afraid, it can turn out okay if you spend the time and have patience.
I think maybe my next project will be this KD89 enlisted original sword that I got a while back...
Thank you ebeeby and Brian for the tips and foresight. Also 911car, maybe you have some leads where I can find sales for ONLY a spike, gods know I'll spend the next 3 years looking for 'only' a spike appropriate ](*,)
