[Trying to figure out if this is a real 1977 gibson es-335]

I bought this guitar off facebook marketplace the other day.  The guy told me he thought it was a replica and I  thought it be a cool wall ornament lol. But, upon looking at it closer, it has a lot of the things that make a Gibson a Gibson .... the truss rod cover, the pins that hold the bridge, the truss rod has the bullet nut and the fret markers going down both sides of the neck as ive seen on other es-335s from the 70s, fret nibs, inside label sticker. However, there are some things that make me curious on whether its fake such as the headstock don't tilt back as much as my les paul and the open "o" on the gibson logo and the dot inlays instead of block are as far as i know not period correct. Im just trying to see if anyone can help shed some light on this situation. If it helps the serial number is 06105417

Any help will be appreciated. Thanks
