Philco 90 Cathedral Question

Hi Everyone, new to this site and I have a simple question.  I buy and sell for fun and I do admit I have very little knowledge of antique tube radios however I do love them.  They offer up a comfort feeling every time I'm around one.  My question is I recently purchased a beautiful Philco 90 Cathedral which I know is a radio alot of folks love, including myself.  what I don't know are what the three knobs represent on the front and does this radio have shortwave.  Someone wants to buy this radio and ask the question regarding shortwave.

Thanks for the help...

I have the answer on the knobs, tuning, 4 point tone, on/off and volume... Just need to get an answer regarding shortwave or not.

This radio does not have short wave. Sorry.................

Appreciate the response... Thanks
