[78-L] Victor's Chicago recordings

[Bryan Wright]

Can anyone tell me when Victor opened a permanent Chicago recording  
studio? Sutton and Nauck, in "American Record Labels and Companies"  
suggest that as late as 1924, Victor was still sending its portable  
field unit when making recordings in Chicago. Considering that  
Brunswick had a Chicago studio as early as 1921, I'm surprised that  
Victor would still be relying on a field unit for recordings there  
three years later.

Thanks,
