I would buy that, but have a vague recollection that an older chrome-plated steel HS I had on a "mystery" frame that also had "COLNAGO" branding on it was ID'd as made by Rino. I could VERY well be mistaken but the HS was definitely not as nice looking as the OP's gold example, I do remember that much!

EDIT: all credit to JDT, I took a look at Velobase and the Ofmega Super Competizione HS sure has a "family resemblance", even to the drillings in the race "skirt".
