This guitar is currently under restoration. It has a carved solid spruce top.
The three-piece tortoishell/pearloid headstock facia was used on the very first Club guitars supplied to Selmer UK.
The Selmer serial # 328 is stamped on the side of the guitar next to the tailpiece mounting. I am assuming that this was the location used prior to Hofner (or Selmer?) deciding that the rear of the headstock was more appropriate.
