Got this bucket from ebay and it was advertised as a Marrow Sun helmet (at least painted).
Not that it matters a ton, since I am pleased with it. Just that I am getting display plaques created and only want to label "Marrow Sun" if probable.
I can upload any additional pics if helpful. The insides looks like rough white/offwhite fiberglass, with a little red over spray. The target finder seems to be wood, attached via butterfly nut.
Thanks for the help.
