Eversharp "Skyline" (?) Pencil

I bought this as "new old stock" and I am trying to learn a little more about it. The paper label on the pencil states "No. J177-BN" and "Use Eversharp Standard Lead". I have found model J177-R" that are called Skyline but I have not found this exact model anywhere.

I believe the way is operates is called "Clutch Action Repeater".

Anything you can tell me will be greatly appreciated.
