[78-L] Quality & Reo - Canadian labels

[Malcolm]

How late was Quality Records pressing 78rpm rock & roll records from US 
masters? And, further, when did Reo - a subsidiary of Quality - cease 
pressing 78s? I'm searching for the elusive "Shu-Rah" by Fats Domino 
which was released as a 45 in the US on Imperial 5734, c. 1961. I'm 
hoping that there may have been a Canadian pressing on 78, but am 
doubtful since the mother and/or master stamper was probably a 45. Of 
course if the stamper depended from tape all bets are off!
Discogs shows virtually nothing about this one.
