I think that should perhaps be Tagliapietra, unless that is someone else.
There's 515 entries for his music in the combined opac.sbn.it catalog, though I'll see how many of them count as substantial works (as opposed to eg. "Tre pezzi per pianoforte" etc.)
I do see a Sonata breve for piano in manuscript (1936) listed...
Also a few other interesting-looking things
"XXVIII ottobre. | (Poema sinfonico.) | in otto quadri" (1933) (parts for very large orchestra held at Biblioteca nazionale Marciana - Venezia - VE)
"Concertino | Per pianoforte e orchestra | Partitura | (Febbraio 1922)" (at Biblioteca nazionale Marciana - Venezia - VE)
"Concerto" also at Venezia (you've mentioned this one)
(Is your Peoma symphony Peoma or Poema?)
"Sanctae Ceciliae | Piccolo poema - musicale per Coro orchestra | e due solisti" (1925)
"Redemptio | piccolo poema per coro di donna | un baritono; quartetto d'archi | organo e pianoforte| di | Gino Tagliapietra | Venezia aprile 1933" (also Venezia)
"Venezia settembre 44 | Preludio e 21 variazioni | sul corale A te a te, Jehova, | voglio cantare" (for piano solo)
"Salmo N. 116 di Davide | per Coro a 4 voci un Sop., solo,quartetto d'archi, | un Corno, piano, arpa e organo | timpano e gong"
e.g.
These look intriguing to me...
