[78-L] Odd Columbia 78s from Argentina

[agp]

Hmmm -- these are odd. This guy has four 7-inch Columbia 78s from 
Argentina on offer on eBay. 7 inch 78s? I looked at his other listing 
and he seems to have a clue but I can't tell if he really means 10 
inch. They are:

Rosemary Clooney - Columbia 1-20.1091

Just seems odd. Any thoughts
