This is not my thread, so please PM me for a response, as I have no intention of hijacking someone's sale thread of a very fine bass.
In your PM, please give some introduction about your experience of vintage Fenders, as there's little mystery about these marks. Having said that, there are some oddities within Fender, particularly the pre-CBS era, where myth and legend do occur, and some acceptance that no-one will ever know, must prevail. Thanks, Rick.

My understanding of the ES mark is that there are a lot of theories about its purpose, but no proof. I'd be interested in your source as well, Rick.
Have another bump, OP. Gorgeous bass.
