[OsvaldoLaviosa]

Hello, I look for various 78 rpm records by Columbia records Italy between years 1946-1959 by Piero Trombetta. I 've already found several titles, but I haven't completed my collection (I can post details about).
The most important one I look for is:

Year 1951

A. "La canzone della mamma" (Trombetta-Frati)

B: "Mendoza" (Costabile-Sibra)
both songs by Luciano Monguzzi (vocals), Piero Trombetta e la sua orchestra tipica di tango argentino.
