I am not about to buy such a frame but I would probably like to find one for myself. The suggestion / inference of murky provenance is not to my liking and is uncalled for.
The reason that I asked this question is that a friend of mine in Italy is gathering material to eventually publish a book on the Italian racing bicycle, a definitive work if you like.
He has a vast knowledge of the subject and a huge amount of information in various forms which he has gathered over many years. He also has personal contact with current and retired frame builders etc. I have limited similar contact but I do not live in Italy.
I do however assist my friend in identifying frames and help him in any way that I can, so that the content of his proposed book will be as accurate as possible.
My friend has a rough but straight 1956 De Rosa frame and fork and it is likely that he will restore it to it's former glory.
In this context, it is essential that the correct decals are used. I do the artwork for unobtainable decals as a hobby and another friend produces these professionally for me.
As far as I'm aware, decals for a 1956 De Rosa frame are not currently available to purchase.
In case you think that I'm "some jerk out to con folks and make a quick quid", you are sadly mistaken.
I have been restoring / rebuilding frames etc. for well over sixty years, including those from the UK, France, USA and Italy, so I do have some knowledge of this subject and in my opinion, I also have decent moral standards.
I know that there were several different De Rosa decals used during the 1950's. and I now know the answers to the questions posed.
I wish you all well; my friend and myself will help you in any we can with your Italian bicycle identification problem.
