There have been multiple versions from Gibson, based on single cutaway LP style body, double cutaway LP Special and SG body; all with a single bridge P90 and single vol/tone controls; all were flat rather than curved top. Early 50's models of the LP single cutaway and "TV" model mid-50s were available in a 3/4 scale body; additionally the original "Melody Maker" was a 3/4 scale single cutaway LP style.
So it varies with year and model - as far as vintage Gibsons went; I wouldn't have a clue as to re-issues, but don't recall seeing a 3/4 scale re-issue, but they may have made some later on. The single cutaway LP is the only one that came in the 3/4 scale, if that's the actual question...
