My D55 had a sticker on top of the sticker (seriously). Evidently the 2nd sticker, which had a bar code on it, was what marked the guitar as a factory second. (There was no big "2" on the back of the headstock or anything.) I suppose that a rather unscrupulous person could just take off both and pretend the original fell out or what have you to disguise it's provenance, so on some of the later Corona builds that might be something to think about (I'm talking about an '04 here).
You bring up an excellent point that I didn't go into in my first post:
The very slight possibility that a guitar didn't have the original neck, which could be easily determined if label and headstock s/n didn't match (Although we've even seen examples of
that from Westerly)
It's conceivable an expert neck swap and re-finish could disguise that, although it's hard to conceive of a Guild that might be "worth" going to such extremes for, if the intent was to try to inflate the value of the instrument.
But some of the Hobokens are starting to show signs of it recently.
I do get the "purist collector" viewpoint though, even though most Guilds don't have an intrinsic "vintage collectible" value like the "other 2 guys".
But hey, if it was supposed to be there when it was built, then it ain't truly 100% original if it's missing.
And for us
real hardcore guys, it's like Rampside said, it's part of the guitar's "personality".
But I wouldn't let it stop
me either, for the right guitar.
Doesn't that Corona have the s/n on the back of the headstock defaced though?
That was supposed to be part of the security to ensure that even if the label DID fall off it would still be recognizable as "non-warranteed"
I assume from you description it was one of the guitars that was refurbished by MIRC. (Photo's too dark for me to see in the soundhole)
