[CR]Help needed on Umberto Dei decal placement

I have recently acquired an early to mid '30 Umberto Dei. I am in the process of having it refinished in the traditional tricolor Dei paint scheme, and have secured (through the help of Stephen Massland) decals from Italy. After talking to a number of knowledgeable list members I have still been unable to definitively establish correct decal placement and, for that matter, which are the correct decals for a bike of this era. The decal set comes with two familiar Dei chainring decals that, without doubt, go on the head and seat tube. However, the set also comes with a fancy 'Umberto Dei Milano" decal that has the chainring and is in the green and red color. This decal can be seen on the downtube of the "1935 mod. Milano-San Remo" bike on the following web page: http://www.blackbirdsf.org/dei/
     However, the decal set also comes with an Umberto Dei signature decal in script with the tail of the final "i" swinging back under the entire name. I can find no pictures of this transfer and have been told that on the 30's bikes this, in fact, may be the correct decal for the down tube rather than the fancier "Milano" decal. Can anybody offer any help. Thanks in advance, Edward Albert Chappaqua, New York
