Can anyone help? Yamaha bass model??

[Rawshank44]

Hey guys, I picked up this bass a few years ago from a friend. It was a bit of an impulse buy and has sat in storage for a while and I'm looking to move it on, I just can't trace a model for it. All I can really tell you is that it's a Yamaha, made in Japan, is fretless, and has badass bass II on the bridge. From what I can see the closest it resembles is a BB1000 but I have little to no knowledge to confirm. Any help would be greatly appreciated!!!

It's a Yamaha BB series. No doubt an expert will be by shortly to give you the exact model. Nice bass!

Anything on the back of the headstock that might indicate the model?

The pickguard would indicate a BB 800....

I could just find this serial number but nothing that could really indicate a model
