[78-L] Another foreign label question

[Bart]

A good number of my disks are made in England.   But since the fellow 
who gave them to me was a bit of collector that may not be 
representative of what was available in stores in the USA in the '30s 
and '20s.  How common was it to have imported disks for sale in the 
usual course of business during the 78rpm era?  Or does the number of 
foreign label disks represent the work of tourists and collectors and 
the like over the intervening decades?
