Cylinder record holder, interested in more information on it

[De Soto Frank]

Hi, any information on these pieces would be helpful. Very interesting early phonograph items. Interested in who may have made them and their age.

Thanks
Dustin

Interesting pencil message on the underside of the crate lid:


" Musicle Dept. [sic]

JW Confer Prof "

Wonder where these artifacts came from...

I think that final letter is a "p," not an "f." (proprietor)
