I agree with Lostarchitect on this, if you recently bought the frame and then shelled out $400 for a paint job your already underwater. While also not being a DeRosa expert I agree something looks odd witht he headbadge.
If you intent is to build that and then sell it don't even think about a profit. It will cost you more to collect a C-Record or early Chrous group and other parts plus time and effort to assemble than you could ever sell it for.
what kind of tubing is the frame made with? This looks like some generic tubing decal
I hope your not planning to use the crankset. someone already went to town polishing it and removed the CampI logo.
