Hi RK, I have an old bandmate friend in San Diego who (I'm 99% sure) bought his AVRI P Bass new in 1986. His bass is black but I seem to remember him telling me that another color was starting to emerge beneath the dings and wear areas. I'll have him check the build dates on his neck and body, the serial number, as well as the finish(es) so that we can see if it is a match to yours. From what I can tell, you appear to have a very very early Corona AVRI - which is totally NOT a bad thing. In fact, my friend still has his AVRI because it's such an outstanding bass. In the 35 years that he's owned the bass I've never seen him without it. His name is Dickie and he calls his bass Tommy (partly because he likes the Smothers Brothers and partly because he plays a lot of Who tunes with his band). He is one of the few bassists I know who can come close to pulling off the Entwistle parts... and maybe the only one who would do so using a P Bass.
