The one exception to this are the "P-" numbered GL's. They were part of an advanced run of about a hundred instruments that were rushed into production. Klein-bodied GK's have two serial numbers: the Steinberger neck number (Nxxxx) and a Klein one on the neck plate.
The best-known Steinberger design is the L-series instrument, sometimes described as shaped like a broom, boat oar, or cricket bat.Later Nashville / post-Newburgh manufactured L's are designated by a 'T' added to the beginning. Bolt-on neck numbers are stamped into the underside of the neck near the heel.This mark also includes the words "STEINBERGER USA".Initially produced as an electric bass and later as a guitar, the instrument was made entirely of the Steinberger Blend, a "proprietary" graphite and carbon-fiber mix in two pieces: the main body and a faceplate (the "blend" being an off-the-shelf carbon fiber "system" from the Du Pont product line).The headstock was eliminated, the tuning hardware instead installed on a tailpiece mounted to the face of the guitar body.We just don't have a large enough sample to see it occur yet.
It's also possible that later in production the numbers were unique, but initial reports are the two separate serial number schemes were not coordinated.
Because of time & labor constraints we are not actively adding serial numbers to the database at this time.
We do have copies of the old manual Steinberger production logs, and later this year we'll be adding the first few instruments produced each month.
Know that for the first run of Klein's the bodies were shipped to the Newburgh plant and assembled there. Note that the one-piece graphite L series Steinbergers have one numbering scheme, and the bolt-ons another.
As orders and production demands at Steinberger Sound increased, all assembly for the GK's was handed over to Klein directly and the appropriate parts were shipped there. Though duplicates do not show on the list, if there's a #485 L2 there also should be a bolt-on with #N0485.
The mass burial took place at a time when the English were battling Viking invaders, say archaeologists who are now trying to verify the identity of the slain.
