Do you remember Gnip – Gnop?

Pronounced "ga-nip ga-nop". Ping Pong spelled backwards. It's a game where each side had three balls and had to get their balls to the other side by pressing levers until all six were on the other side to win. Having a childhood flashback and was wondering if anyone else played it? I had a conversation with a friend about it, but he didn't even know what pickup sticks where so I reached a dead end there.  After spelling it wrong on a search engine I finally found it at the feeling retro site. Think I have to go to eBay and get one now. Parker Brothers 1971 - here I come
