Intake Manifold Identification

[David Cleveland]

Can anyone identify this intake manifold for me? I inheritated it with my truck when I bought it but there's no markings on it anywhere.
It looks like a Weiand action plus but it must be an older design if it is because there's some differences. Just trying to decide if I should use it or sell it.
Thanks.

Edelbrock LD4B? Weiand markings are depressed, so would be difficult to delete; whereas Edelbrock is raised and would be easier to shave.
