[Hallicrafters] S-53

[Ginger Harris]

I recently added to my collection the humblest Hallicrafters I have  
ever seen, the S-53.  I think it is an early version as the date  
stamped inside is  August 15, 1947.  A Hallicrafters picture gallery  
called the production from 1948.  All the pictures I have seen show  
the big  plastic knobs  with a metal ring insert ( over an inch and a  
half  in diameter on mine), and the smaller knobs, which on my  
version are a bit over ll/16 inch in diameter.  And they are made of  
machined aluminum.  I think the pictures I have seen  of the S-53A  
and the S-53AU show a larger and perhaps less metallic small knob.     
Can anyone confirm this?

It appears that someone changed out the band switch, which is where I  
am missing one of the little aluminum knobs.  Any chance someone has  
a source for these old knobs or a parted radio?

Thanks,

JP
