I've had these in my collection for a decade and the 'Tank' thread made me open the box.
Maybe you can tell me the story of the one in the upper left. It has the same marking, a "T" , but hotstamp says
Ching Powerline ...Putter Approach [USG-0-] Super Stable Chain Crusher
and has the same dome as #119 & #120. The 3 Y2K Special Edition have a very flat top.
Also a question about the very early runs of the Omega Supersoft. The 1.2, 1.3, 1.4 and a few other runs were a real 'pebbly' plastic. What is the story and is that effect reproducible?
As always, Thanks for your time
