Unknown Silvertone. Help!!

This was given to me by a friend. I am trying to find out some info, model, year, whatever info I can get. The fretboard looks to be maple, but someone has stained every other fret with a darker stain and in the process, destroyed the frets. I have not seen another headstock with a logo like this. You can also see that the machine peg holes were bot drilled large enough for any type of guide or ferrell. It looks like at time it may have had a plate of some kind screwed to the face of the headstock for a peg guide. I am thinking about stripping this, repaired the wood damage and restoring it to a playable guitar, for a conversation piece if nothing else. I don't want to do this if it is a rare or collectable guitar.
