RayBan Justin not like my others

I have a perfect pair for the car but I needed to replace my workplace RB justins after 4 years on the job. Bought these from eBay. Sold as used but in very good condition. The seller is quite sure there original but I'm quite sure about that. Few things don't look rite. Hinge screws, lense engraving, inner labelling, poor finish around side logo ECT.

I'm sure there are some professional here that can help me. Thanks
