I bought the exact same lefty brand new, just four-string rather than 5, in about 2004. Hard to remember exactly how much I paid, but I’d guess £300.
Although it was a nice instrument to own, and my main bass for years, I was never happy with the sound. I bypassed the active circuit, but in hindsight the pickups were probably to blame.
I wish I still had that bass. Congrats to you.
