Richard L. and Seanychen,

I have the same opinion, FW190 or D9 spinner is the best alternatives
if no Zero spinner available.
I don't know mass produced Zero spinners for 120 size.
For 60 or 40 size, some shops in Japan still seem to have one from Marutaka
in stock. It's aluminum rolled spinners.
This is 40 size one came with the kit.
This color scheme is said for paint saving purpose.
