That is a paint stand, not a fuselage jig. Here is a scan of Byron Barker's original fuselage jig.
The specs were:
Builds bodies 48" long-6" wide
Comes with 6 pair angles squares with 3/8" slots
Extra 4"X4" angles squares available.
$150 plus shipping and handling.
He also built wing jigs and profile fuselage alignment jigs.
