This wonderful guitar is one of the few surviving examples of the pre-production models built by Selmer under the direction of Mario Maccafferi. The Selmer log book only lists a handful of the first hundred guitars they produced as official record keeping didn't start until they reached serial #100. These pre-production models are exceedingly rare and for that reason, are highly coveted by collectors and players. Pre-production models all have serial numbers below 100 and usually share the following traits: - An engraved bakelite label mounted on the internal resonator - The serial number is engraved on the top of the headstock -The headstock displays Maccaferri's name along with "PAT. Nº 10.431" -A stair stepped tailpiece with an ebony saddle and tortoise insert (later models have the more typical rounded tailpiece with a ebonite insert.) -no fingerboard dots (this guitar had fingerboard inlays and dots added later.) Additionally, this particular example was constructed with macassar ebony back and sides which, to my knowledge, makes it the only Selmer ever built using macassar ebony.
