Vintage Colnago MEXICO Oro Road Bike Frame Fork 53 - Rare Frameset

Description

Colnago Mexico Oro Frame and Fork.
Size - 53.5 measured from center head tube to center seat tube.
Frame # P29
I had this frameset stored away for over 15 years.  Purchased and shipped from Italy during my bike collecting days.  My original intention of restoration will likely not happen so letting it go for sale.
The frame is straight no bent or crack.  There is a ding on the right chain stay near the bottom bracket (red circled in picture).  There are 2 additional holes for water bottle insert on seat tube (red arrows in picture).
Not sure what other information to include so please message with questions.  Not sure what is it worth now so will take best offer.  The frameset will be well packaged for shipping.
Will also list some vintage parts soon.
Please look at detail pictures.
