[78-L] Need info about Columbia T-series circa 1912

[Adam Miller]

Hi,

I have several Columbia Phonograph Co 78s (so pre-Jan 1913) which all
bear the incription at the base: 
"PATENTES BRAZILEIRAS 6165, 6166"
which implies they were pressed there for the South American market.

They have serial numbers in the T3xx to T7xx range.
A scan is at http://www.78rpm.net.nz/78s/images/GORI%201912.jpg
and a second at http://www.78rpm.net.nz/78s/images/de%20bassi.jpg

Two have Argentinian copyright stamps, the ilustrated one has an Italian one.

I just want to confirm if they are Brazilian pressings.

Thanks

Adam.
