That´s not the only one ! Here is a pic of my friend Hans´ NOS Yenko-block with the Winters-logo.
I´m not an expert on these blocks, but I haven´t heard that story before. I believe Yenko bought the tools to make the ZL1-blocks, then changed them to make the blocks more durable. If Winters made these blocks, and they did, why not have the Winters-logo on them ?

Now I can safely say that this is the first ZL-1 block
I've seen with the Winters logo in that position......
