[CW] 1915 New York Herald Radio WHB PX (Spark)

[Richard Knoppow]

    Your aluminum discs may be embossed recordings. These play with a 
much larger than standard stylus. They were likely not made by NBC Radio 
Recording division but by an independent company.
    I believe Apgar's recordings were made on cylinders. Not sure but I 
believe I have seen a picture somewhere of his setup. disc recording on 
wax by an individual would have been quite unusual at the time but I 
beleve cylinder recording was available.
