Need help with a mystery Rossin frame please

I just picked up this Rossin Quattro frame and it is a mystery to me. Every Quattro frame I have seen with crimped tubing is white and red. This one seems to have been originally green and yellow. I have searched everywhere for anything on a Quattro frame in green and yellow and have found nothing. Can anyone shed some light on this one? When I purchased it the story I was told was that the seller used to purchase parts from the Rossin factory and this frame came with others he had purchased in this condition. Apparently Rossin sandblasted it then let it sit until sold. I can only assume they painted it the green yellow then decided they didn't like it or that they were not going to offer that color combination. It still has traces of green and yellow on various places and pink at the head tube. Also would you think it should have the Quattro fork? There are no serial numbers on this one only 58 stamped on the B/B. I have two other Rossins and none of them have serial numbers. I included a picture of a green and yellow frame and a Quattro for reference. Please note that although it is a Quattro frame the remaining decal on the chain stay is not Quattro. The overall weight as it sits is 3.5lbs.

I am trying to figure out it's original configuration so it can be put back to original. I have searched the internet and found nothing. Any help would be appreciated. Thank you.

I have one of those frames, I believe from the same seller and purchased in 2020.
Mine is almost identical to yours with exception of the paint. Mine just had a little blue left on it.
Every other detail that I can see including the size is identical.
I put a carbon 1 inch fork on it and used as many other light weight carbon parts as II could find.
I used a Campy Super Record 11-speed groupset on it and the weight was about 18.5 lbs.
Rode it for a few years without painting it because I was having too much fun on it to strip it back down and paint it.
It is now in the process of being painted. I will share when I am done.
