Have just purchased a Lovely Gibson LGO (Headstock Number 27723) and I know that this is the place to find out about it !! Have tried various Gibson Web sites, but, their numbering systems are bizarre to say the least! Can anyone head me in the right direction? It's Mahogany, with a tortoishell banding round the top, all the bits seem to be original, has obviously gigged a bit, so a bit of wear and tear, but, not too much. Plays like a dream though! And finally...What do you think it might be worth (and then I'll tell you what I paid for it!)
