Is this Wilcox L4 G11 mount genuine?

I bought this Wilcox L4 G11 on eBay from a seller with an excellent reputation but the printing on the mount differs from what I see online. Matter of fact I cant seem to find one photo of this mount with the Wilcox logo situated where it is on my mount. I also noticed it didn't have the NSN number.

The mount seems solid. I wouldn’t expect an airsoft clone to be this well made but if it’s a fake I’d like to get it back to the seller ASAP.

For those of you who have experience with these mounts can you please weigh in?

Thanks.
