Just found out,Paul already have looked into this!
Found a Nos Tange MX3 & Nos incomplete(seems)Tange Seiki 303.
The 303 = missing the anodized Gold Lockring,so iĀ“m glad the MX3 has the Gold Lockring.
To make the 303 complete again.....
(this is a borrowed pickie, for compare reasonĀ“s only,so: please dont ask)
