Can you help tell me whether the attached pics show a standard, standard-plus, plain-top or something else, etc?

The seller says that the truss rod cover is a replacement from a Studio, which is why it says studio even though it says Standard on the back of the neck.
It says Studio on the truss rod cover, but then says "LP Standard" in the sticker on the back.

...I'm confused...
That is definatly a Standard, it looks like the truss rod cover has been replaced at somepoint.

You can tell its not a studio because studios dont have a maple cap or binding, this does so its a standard.
