The NS-Body is the curved body design that SPECTOR is best known for. In 1976 Ned Steinberger, a furniture and cabinet maker who shared space with Stuart Spector in the Brooklyn Woodworkers Cooperative, became interested in designing a bass guitar for Stuart.
Ned had been working to build curved furniture, using wood's naturally organic shapes to create furniture that was rounded and not squared. When Stuart damaged the neck on a SPECTOR SB-1 bass, the first commercial bass made by Spector Guitars, Ned asked if he could have the ruined body to "build you a new bass design". Stuart handed it to him and said, "Be my guest".
Ned, who is not a musician, looked at the instrument from a purely functional viewpoint. He shaved down the bulbous SB-1 Body and contoured it. Using blocks of wood like what is used in a butcher's block, he kept the SB-1's horn shape and little else.
A week later he returned to Stuart with the NS-Body prototype.
The NS-1 (NS standing for Ned Steinberger) went into production in 1977 and made history.
It was Ned's first instrument design. Not being a musician or having played bass guitar before, it was like someone who had never seen or played baseball before walking into Yankee Stadium and hitting a home-run out of the park with their very first time at bat.
Ned would go on to deconstruct the modern electric bass and guitar and give us the headless Steinberger bass a couple of years later. All of this because of his friendship with Stuart. The two remain close friends to this day... as a matter of fact all of NS-Design's classical/electric instruments are made at the SPECTOR Czech factory... they share the factory together.
All of this happened before Hans Peter Wilfer started Warwick in 1982.
Funny, but Hans has always had a love of Ned Steinberger's work. The very first Warwick was a copy of Ned's famous headless bass...
From there he moved to his most commercially successful design... a complete, identical copy of the SPECTOR NS-Body bass... Warwick called this bass the "Streamer".
It was such a complete knock-off/clone of the SPECTOR NS-Bass that the original Streamers even had the EXACT same headstock shape:
And BTW: I discovered where that funky Hipshot bridge came from that's on that "NS-2" that's on Ebay (that we all know isn't an NS-2)... It's the Leo Quan copy that Warwick used on their NS-2 knock-offs back in the 1980's. That answers that.
So to answer your question... Yes. The SPECTOR NS-Body, NS-Shape, NS-Bass, refers to the FIRST bass guitar in history with a fully carved, curved body.
Anything Warwick has done is simply a copy of.
Congrats, I dont know you personally but being a Spector nut, I know of you, as you are like a Spector household name. 
That bass is beautiful!!!!
