[CR]Real or Fake Panto?

I recently bought a 1970's Colnago and I'd like to dress it up with a few early panto items. The following eBay seller has a neat stem but the size of the "Colnago" writing on the side is somewhat larger than what I'm used to seeing for this vintage. Then I got to looking at his other auctions and it seems he has an unusually high number of panto items.

Below are some links to some of his current & sold items in the last month or two. There are so many and in styles I've never seen that I'm concerned that the pantos have been added recently. I would rather be wrong about all this because I like some of it. But I don't want to pay real money for something that's been recently created to look old & original.

Here's the Colnago stem I have an interest in: http://tinyurl.com/3troqz

He had another one just like it a week or two ago: http://tinyurl.com/52rdjt

How about handlebars with this Colnago logo engraved on them? http://tinyurl.com/4fkzfn

Campy Super Record Colnago rear derailleur? http://tinyurl.com/4qrcqx

Bianchi chainring that looks like this? http://tinyurl.com/4mh9et

Colnago shift levers. He's sold several pairs of these. The flat surfaces look much fresher than the rest of the shifter: http://tinyurl.com/3emfoh

Old Campy pedals with panto & newer signature? http://tinyurl.com/3suw5t

Would DeRosa do it this way? http://tinyurl.com/54nl82

More DeRosa. Pedals: http://tinyurl.com/4sfprs

Same picture, different auction for Colnago shifters. Is he manufacturing these...? http://tinyurl.com/4jth6k

Another very odd style Colnago panto item. Shift levers: http://tinyurl.com/3h6eup

I've never seen a Masi seatpost look like this: http://tinyurl.com/3nasuy

There's more but you get the point. Thoughts & comments? Should I bet the farm or run the other way?
