Need help dating my new old colnago

I just picked up this bike from an old bike shop in NYC.. It had been up on the wall for 20+ years they said. I loved it from the start so I offered to buy it. It looks to be all original but what do I know.. I emailed Colnago some pics and this is what they said.

"Thank you for reaching out to Colnago. Based on the photos of the frame and the description, this looks to be an early 70s (most likely 1972) Colnago Super Pista. It was built with Columbus SL and SP tube sets and has a sticker on the seat tube commemorating the hour record set by Eddy Merckx in 1972. This is a beautiful frame with very unique lug work that is typical of classic Colnago frames. If you have any more questions about Colnago products or services,please contact your local authorized Colnago dealer.

I know theirs tons of COLNAGO guys who really know. I just want to make sure. I will NOT be changing anything on this bike only the tires as they look to have a little dry rot on them. I will clean it up a bit to restore it to it's original glory.

Please Help.... Yes I will adjust the bars to their proper position. Take a look at some pics.

Thanks for your help
