Is this speaker an Eminence Vintage Shadow/VS-12/V50/etc

[phyrexia]

Here are two pictures of what I think is a Vintage Shadow. These pictures are about 1.4MB each.

Any help? Don't want to sell it as one speaker if it's not.

Thanks
Victor

It doesn't have a label and it doesn't have any stampings on the frame. On the back of the cone is '1257-1'
