###Yes. There is. 

I have a few. They are really bad for connecting to things.

Like, BanBao bad. I can't really use them for anything.

But at least they have the blobs. Yay. What a collector's item.

Nobody wants them on BrickLink. 

But yes, there are those, and they are rare, for the same reason the "Pat Pend" ones are rare, mostly the age, and short transition period.
