P-155 Edison Gear Cover. Original. Goes on the Edison STANDARD cylinder phonograph Model A, and Model B (not the “Tall Standard” with the combination attachment).
Note: The Edison Standard Model B, the “Tall Standard” with the combination attachment, takes the stock item # P-155b.
Additionally: The Model A, B or C machine with STANDARD Combination Attachment fitted to it may be readily distinguished from Combination Model D, as gear covers of Combination Attachment Outfits slope toward the rear of the phonograph, while those on Model D and later have horizontal tops.
