[78-L] Long playing early lacquer

[David Lennick]

I've just played an early lacquer 78RPM aircheck (July 1934) that runs four 
minutes and fifty seconds AND has a large label, meaning that at least another 
minute could have been accommodated. It looks almost microgroove. This was cut 
by Sound Reproductions, 67 West 44th Street, New York. Was anyone using a 
really small groove experimentally at that time? Edward Wallerstein says this 
was happening, in a memoir that a few people have questioned for credibility 
and timelines.
