[Excess glue inside guitar need help]

Well, honestly, I think Gibson would do well to avoid this sloppiness - they slip a few too many through with minor issues. But it's part of what Gibson is, I suppose. Take it in stride and enjoy your guitar.

[1970s ES-335]

Cool.

[1970s ES-335]

Is that guitar a 335? It has a tail piece like used on a hollow body rather than the stop bar I'm accustomed to seeing on 335s? Maybe in the 70s they used that design?

That thing looks mint. Gibson history right there.
