    Can anyone identify this guitar from the headstock please? The guitar is strung for a left handed player. Is it OK to just change the nut and and modify the bridge for a right handed player? Would it have been made differently as a left handed guitar? ThanksEarly Gibson Archtop ID-unknown-gibson-archtop-headstock-jpg

    Need to see a picture of the whole guitar. Yes, all you do is change the nut and bridge the bracing is whatever it happens to be, that would not be a factor at least in the conversion. To me it looks like an old L4 or maybe L7 but clearly a smaller archtop.

    Thanks. Here's the front!
    I've now seen a very similar one on YT as an L4!

    If it's 17" in the lower bout I'd say L7, but 16" would probably be L4.

    Thanks. A very comprehensive website on early Gibson specs suggests that a '33/'34 L7 had no 1st fret marker whereas the L4 did.

    I’m pretty sure that’s a ‘32-34 L4. They had 24 3/4” scales and 1 3/4” nuts and were were basically plainer versions of a 16” L5. IIRC, both the headstock inlay and fingerboard inlays (which did include one at the nut on the 7 but not the 4) were unique to this very limited run model and the L4s made in the same years. Those FB inlays are a bit fancier than those on a 16” L5 despite the otherwise lower trim level, and the 7 has 8 of them while the 4 has 6. I think they may have been used by Gibson on a Nick Lucas banjo too.

    Here’s an L7 -

    And here’s a ‘34 L4 (both were on archtop.com a while ago):

    Thanks. Do you know what that went for?

    No, I don’t - sorry. BTW, I corrected a few small errors in my post. I remembered the FB inlays backwards. The L4 has none between the nut & first fret and none between 16 & 17, so this one’s an L4 and not an L7.

    I also added that those inlays were probably the same as or very similar to ones used on the Nick Lucas banjo. I think the Nick Lucas guitar also had them.

    suggests the L7 is the one that doesn't have the first fret marker. Guitarhq.com 'confirms' it as well.

    The 16” f-hole L-7 and the early 16” f-hole L-4 are essentially the same guitar. When the L-7 became upsized to 17” in basically 1935, the L-4 went from being a round hole to an f-hole guitar and was for all intents and purposes the same guitar as the 16” L-7. Eventually it became a bit different with a flush fingerboard neck joint.

    There are several conflicting posts and videos out there. This one is about a ‘34 L4 and it has 8 fretboard markers:


    Here’s a ‘34 L7 with 6 markers -

    Maybe there were 4s and 7s made with both boards - who knows? Gibson was clearly raiding parts bins from day 1. We don’t even know if these guitars are correctly identified, so nothing is certain. I think it makes sense that the 7 would have more or fancier trim that the 4. But we’ll never know.

    The 8 marker boards look like they could be ebony, while the 6 marker boards appear lighter and more like RW. It’s another mystery!

    I saw the Silly Moustache one. The Guitarhq website (to which I couldn't seem to link) is very specific about which has what. Don't know how reliable it is though but it has a lot of detailed info. Vintage Guitars Info - Gibson archtop vintage guitar collecting - Ah! it's worked now!

    They are all almost certainly rosewood.

    Currently the 16” L-7 goes for probably 5-6k. For whatever reason if labeled L-4, they always seem to bring less.
