This sounds interesting.  What was the 1935 device?  I can't find any other text on this subject [1935 home recording advice] from anyone.

Thanks for the responses. One of you even went so far to get Seth W. to

Ward has offered to do the discs. Both Seth and Ward recommended a large

Thanks so much.
