Picture 1, Row 4: The first bass looks like an Alembic but may be a Fernandez. The third bass is the Persuader in picture 2.
Picture 2, Row 2: Second bass looks possible.
Picture 2, Rows 4&5 squished together: First bass Quilted Maple Mark King. Second bass looks to be the same Fernandez as was in the first picture (the logo just doesn't look right, and other features look like the standard Fernandez copy from that period).
Picture 2, Row 6: First bass Quilted Maple Persuader.
Picture 3: Triple-O Mark King. Flame Maple Persuader with Vector body. Same Maple Mark King as in Picture 2.
Picture 4, Row 2: Third bass may be the Fernandez again.
Picture 4, Row 5: The Maple Persuader again.
Picture 4, Row 6: Excel.
Picture 5: N/A.
So; Quilted Maple Mark King Standard, Quilted Maple Persuader, Triple-O Mark King, Flame Maple Persuader Vector, Excel.
So I'm seeing 5 definite Alembics.
