I don't think Eppi used the two different style tuners at the same time. I think they switched from the long straight shaft to the short Taper shaft around July or August of 2017. The link I sent had a pretty poor quality picture. I couldn't read the serial number, but the FB looked kinda dark and I thought the tuners looked kinda like straight shafts.Unless they used both kinds of tuners early on, I think that's a later version with the tuners now being used. (See examples below.)
That said, you bring up a good point, at the very least the tuners look shorter than the early VPs used, and they might in fact be tapers as well, hard to tell from the picture. I do know that some folks were installing after market tuners (Hipshots I think) that had shorter straight shafts and looked more like vintage Gibson tuners from the 1960's. Maybe that's what this is.
Also, judging from the gold SN decal it appears the bass has been reconditioned or refinished by the factory or their representative. Might still be a good deal, might not. I can't even tell from the pictures if the neck is actually blackened with use or if it's just a shadow from a lousy picture.
If I were in the market for a used white one I'd consider it but I'd confirm the weight is ok and that it hasn't been refinished.
