What set does this knob this goes with ?
 

I've been sorting through some knobs and came across this odd looking one with channel #1. Any ideas ?

I have no idea what it's for but am wondering if that's the knob or the bezel?
It seems that another knob with a pointer might go inside it?
Or possibly it went behind a mask with a window so only one number at a time showed?

You're right, the hold through the center is smooth so a shaft could rotate through it.

Sparton Mirror in Lid 4900 or 4940. It rotates inside the large round windowed raised gold bezel. Here is a link to one on Chuck's site:

Cool, mystery solved :)

The caption for the Sparton mirror-in-lid TV says it has a 12 channel tuner. the mystery item features numbers 1 through 13.

Also the numbers would be upside down with the channel window in that location.

I think the general idea is correct though, it was used in something like this, perhaps a different Sparton, one with the window on the bottom?

Bob,

Next time you are in the Early Television Museum, you might look at their 1949 Sparton:

Click on the image to enlarge, then click again and it will expand more. I believe that is your knob.

The FCC dropped channel 1 in 1948, but several sets still had the obsolete channel in 1949.

This could simply be an early production 1949 set.

I think that this knob rotated, but since it had to be aligned to the tuner shaft and the window, it was held in place with a spring clamp outside the plastic.

Here we go. Maybe you also have the missing channel knob that goes to this set?

Looks like this set has the outer part with the channel #s but they stuck a 'tone' knob in the center.

Wouldn't mind getting one someday, but this one is a little too rough and far away.
