    Nice project.

    But hot hide glue has a working time of 30 seconds or thereabouts. The liquid hideglue does have an open time of what you say......not anywhere as strong of course.

    Kris,
    Yes the serial is in the 185xxx series.
    Guitar dater placed it from 1970-1972 by serial#.
    The les paul signature model is silkscrened and the gibson inlay has closed b and o with the dot on the I.
    Being a cherry burst puts it after 1970.
    Having silkscreen before mid 1972 I believe.
    Almost every part has been changed on this thing except the switch and the knobs I think they are original.
    it's really hard to date these old guitars.

    LPC,
    I played it for about a month before starting the repair work. It has a really fast thin neck which I prefer.
    This guitar has a really woody sound, almost honks at you with a lot of sustain. Similar to zztop just got paid today sound.

    ARandall,
    Yeah you are right.
    I changed it to under a min.
    As long as the glue hasn't gelled it will work.
    Always test fit and do a dry run before any glue is applied.

    Good job :yesway:

    This looks like it could be the twin to mine which is (by consensus on this forum) most probably a '71 or early '72 - except mine has a fairly fat neck, and didn't come quite as dirty as this one.

    I especially note the routing for the wiring channel in the control cavity, where the channel sits closer to the lower pot than they did later on.

    ...what would be really nice would be a closeup of the headstock, because apparently there are several distinctive logo shapes in the early 70's era that make identification a bit easier.

    But the wiring channel sits low?

    I always assumed that it started off low in the cavity and then moved upwards as the years went by - until the drilled channel appeared...

    Has been discredited by many sources.

    So far in the sea of Norlin confusion..the 1XXXXX range has been consistent to '73-'74.
    The ERO II caps and pot code nail it for me as well.

    wiring channel in middle location. In the move upward post 1974. No doubt a 73-74.

    Yes, in 1968 they/it were down low next to the bridge VOL.pot. In 1973 mid/late they/it started the move up.

    This is '71 logo:
    upload_2017-9-11_9-5-57.jpeg
    upload_2017-9-11_9-1-55.jpeg

    The key is the squareness..this went into '72, then became the logo that yours has.

    Really..doesn't matter..still Kzoo made! Still amazing LP..but is a '73..(MAYBE '74..pot code is very late in year)

    Interesting... Really interesting thread. I have an all original (except for the output jack plastic and frets) '72 Les Paul Deluxe. I know it's a '72 as this was the only they had the "Gibson" embossed pickup covers. Obviously, the OP wouldn't have those as his pickups have been replaced, but I'll see if I can find any other identifying marks when I get home from work.

    To the OP - If you're still having difficulty cleaning gunk off the finish, try P21S Paintworks Cleanser. It's an automotive product that works really well on nitro finishes that need a lot of help, is silicone-free and won't eat through the finish. http://www.p21s.com/products/bis_pc.html
