[Eliot Ness]

I'm going to encourage you to keep and restore this radio.  Most of us would give our eye teeth for a radio that belonged to our grandparents, and once it's gone it's gone..... lost is the possibility of passing it down to your children or grandchildren.

If you do decide to sell it I would sell it "as-is", since most collectors would prefer to do the restoration work themselves and you'll seldom make back what you spend in time and parts.   I can't help you with a value, but you are out west where radios are not as plentiful.  While that might be a factor in your favor, that radios real value is the sentimental connection to your grandfather.

If you decide to restore we'll be more than glad to help you out, but please don't power it on again or you risk damaging it further.  Those capacitors are 75 years old and way past due for replacement.
