Hey freemandnj973.
Sorry you've had no luck getting a manufacturer ID on your Les Paul copy so far, but these guitars are almost impossible to ID without some very specific information. First, you must realize that any company that ever built a copy guitar had a Les Paul copy in their line. So we are talking about hundreds (if not thousands) of potential builders. Many of these companies also sourced hardware from the same sources so a general "look see" at the instrument is not much help.
The good news for you is that your guitar has a fairly unique headstock shape, that helps with an ID, but a clear picture of the entire headstock would help more. A picture of the neck plate is also sometimes useful. Is the guitar solid wood, or plywood? The more detailed pictures you can include the better the chances that someone may recognize who built your guitar. The brand name on the headstock is just a distributor and doesn't tell us much about the true builder.
As far as restoration, that is a nasty crack in the neck. I don't see a cost effective way to repair it. If you replace the neck, it's not the same guitar. If you love it for sentimental value, hang it on the wall "as is" and love it. If you want to play it, I suggest buying a different instrument that's similar. I don't think you would ever recover the cost of a repair to fix it.
As usual, just my opinions.
