Missing RAI tapes of Unsung Italian Composers

[miklos]

Many RAI tapes were available in the US for purposes of radio play and many were broadcast and recorded. Many of these tapes have been circulating among collectors for decades. But a number of others were either not broadcast or not recorded by anyone, at least I have never seen them. I know of their existence from the catalog that accompanied the tapes.
Here is a partial list of those "missing" RAI tapes. All are orchestral or vocal-orchestral works.  Perhaps some member of this site has some of them:

Renzo Bossi, "Vibrazioni"
Orazio Fiume, Canto Funebre
Carlo Franci, Vibraphone-Marimba Concerto
Sandro Fuga, Trumpet Concertino (This was once promised to me by the composer's daughter, but she never sent it)
Terenzio Gargiulo, Oboe  Concertino / Serenade
Guido Guerrini, Variations on a Sarabande of Corelli
Mario Labroca, Madrigals for Orch.
Lino Liviabella, Symphony for Voice & Orch. (After T.S.Eliott)
Franco Margola, Fantasia on Ahmaric Themes
Virgilio Mortari, Varriations
Riccardo Nielsen, Sonatina for Piano & Orch.
Flavio Testi, "Crocifissione"
Gian Carlo Tocchi, "Luna Park" Ballet Suite
Mario Zafred, "Duino"-Cho. & Orch.
Ottavio Ziino, Piccola Sinfonia Concertante

These guys are almost all conservative 20th century composers and surely qualify as unsung, although a few like Margola have been turning up lately on CD.
I would love to know if anyone has any of the music on this list.
