What make is that guitar? The only Black Widow named guitar I can find on the net is this Schecter,only made in 2005. Obviously not the same guitar.
Edit- Aha,I found it. A 1970s Black Widow, designed by Paul Barth.
This is one of the common Japanese production models made for the Acoustic Control Corporation.Not quite the same as the one you have pictured. There's a few references on the net that Mosrite also made a few Black Widow style guitars for Paul Barth. I think there's a good chance that yours could be one of those. The paint job definately looks very much like something Mosrite would do,along with the added pickguard. Am I seeing some additional switches in the pickguard? I wouldn't be messing with that guitar until you know exactly what you have.More research needs to be done.That could be an extremely rare guitar. Here's a Black Widow page that mentions the Mosrite connection.
Edit again - Here's an example of a an original Mosrite done custom metalic burst paint job. You can see the similarity. I've also seen some origianl Mosrite done custom paint jobs that have the automotive type graphics on them such as pinstriping and racing stripe, like on your guitar.
