Vintage Washburn Bass ??

Hi, all. I am searching for a particular wasburn bass from the late 70s. I owned one of these from I guess about '77 thru '81. I have no idea what the model number or name was. It was a through neck & the finish was a really nice two or three tone natural. All I really remember about it was that it sounded nice & was heavy as hell. I would like to try to locate one of these for sentimental purposes or even see a photo of one if anyone here has a clue what guitar I'm describing.

 

I figured out that the guitar was a Wasburn Vulture or Vulture II. Guess I had the years off a little. Seems like it must have been made about '79. I would like to buy or trade for one of these if I can find a bargain. I really don't think they are worth very much, but it was one of the first basses I owned so I would like to have one to keep.
