wait a second as I mentioned with my experience with a Zim Gar marcher with Die Casts..... They were die cast- Visually- but not ANYWHERE - near what (today's) Pearl, Gretsch die cast are. In stiffness I could BEND the Zim Gar hoop with LIGHT HAND PRESSURE. So yes may have cost more for them at the time; BUT NOT same Quality not in same league as Gretsch later Pearl etc.
glad I cleared that up :) (one more thing. that zim-gar marcher in excellent shape, with die cast was JUNK) a useless soft amateur drum) looked the part. looks only.
I twisted (when I had it off...) the hoop with my bare hands! Light pressure!! :):):):)
had to twist it back. like it was bubblegum. taffy.
