Just a heads up here, Bill Mcbride has just outed this on FB saying he's suspicious of this auction. He won't verify whether the saber is real and he's also found a second auction here:

I know they are different Sabres, one is BB and one is L, but the writing style is obviously the same, and Bills point is why would anyone list something so rare on different accounts if it was all above board and legit. These things sell themselves, so why the games? Plus, more importantly, he won't verify either is legit, at least from the photos.
The guy has some great stuff, and decent recent feedback so not sure what's going on. Could all be perfectly fine, but worth a second look before diving in
