Geeto, have you or anyone you know ever actually been in the same room as one of these fabled Giuliari F seats?
I tend to think the 2 people that bought them lost the seat before they ever got around to putting it on their bike.
I have one. It is in my storage unit in NY. I had it mounted at one point on an old F I have but I don't seem to have any of those old pictures. I don't have a stock framed F at the moment but I am holding on to it because I'll probably buy another one sooner or later.
Mine has the black seat cover and has been def used. It has a gold paint job with black stripes. I bought it from a T500 collector/racer friend of mine who was going to cut it up to mount it on a T500, when I explained the rarity of it he sold it to me. He had it for something close to 20 years, he buys a lot of giuliari seats to use on two stroke suzukis, I'm in the middle of trying to convince him not to cut up a bmw airhead one for a T500 so I can use it on my R80.
do you have questions about it? I can answer most questions. I have seen three other ones in my life, plus two others for sale on ebay in germany and italy. The one with the white cover I posted a pic of is owned by someone I know and I forwarded the info to the OP in case he wants to try to convince them to sell it. As far as I know that one has not been used. There is an old thread on these seats here that even discloses who owns the white one:

The white giuliari seat covers are pretty durable. They don't turn brown or get dusty, the worst that happens to them is they dry and rip (they are not the highest quality vinyl), and dirt gets into the cracks and start to make it look grungy. If you smoke around them they will yellow. I have seen a number of harley and vespa seats in white that giuliari made and this is about as bad as they get if you take care of them:
I had entertained the idea of reproducing them. The rear cowl is just old fashioned chopper gun hand laid fiberglass, and the seat pan doesn't look to be much different. The hardest thing to source would be the foam. For what it would cost I don't think there is a market to support it.
I personally like them because they remind me of the BEET bodywork you see on a lot of the Japanese Domestic custom KZ1000s and CB750s:
