Big Bird Wind-Up Alarm Clock

[blessedpsycho]

Hi there! I just have a quick question, and want to see if anyone here might have the answer to it.

Last year for Christmas, my mom gave me a Big Bird alarm clock, and I fell in love with it instantly. If you've never seen it, here's a picture I found online of a better looking version of it than mine:

Mine, however is missing the alarm key (but the clock key un-screws, and I can use it for both), what appears to be water damage to the clock face, and a couple of small rust stains.

Anyway, my question is about the lever on the bottom. In the back and bottom of the clock is a little lever that switches between the letters "S" and "F".

So, does anyone know exactly what it does? I haven't been able to figure that out in the last year, and it's slightly bugging me. Any help would be fantastic. Thanks in advance!

Oh man, that is one retro clock. That would be awesome for my bedroom, Along with my goblets and toaster.

Goblets and a toaster, that is so cool!

I love that clock, I have a simelar Mickey Mouse one, well- same sort of style. Argh, it doesn't even work. But that Big Bird one is awesome, it must be a rarity, huh?
