Gretsch "Studio" Black Nitron kit

Phil Collins has a Gretsch black gloss-finished double-headed drum kit, which he purchased new in 1976 roughly six years before becoming a Gretsch endorsee.

As seen in photos of the time, Phil played the Gretsch drum kit during November 1976 rehearsals with Genesis for the Wind And Wuthering tour, albeit extended with Premier concert toms and Remo Rototoms on the side. In the end, however, he preferred using the Premier concert toms for the tour and supposedly lifted the bass drum from this kit.

Looking at the drum sizes in particular (see below), the kit doesn't seem to match any of the drum outfits in the 1977 Gretsch drum catalog...

Drum sizes

 * 12" x 8" rack tom
 * 13" x 9" rack tom
 * 14" x 10" rack tom
 * 16" x 16" floor tom
 * 18" x 16" floor tom
 * 20" bass drum

Based on these sizes, the setup doesn't seem to match any of the drum outfits from the 1977 Gretsch drum catalogue.
