Identity of 4 Barrel Intake

[odieundun67]

This aluminum intake was sold to me for my 231 Cu. In. Buick V6. It has a spreadbore pattern on it. I had planned to replace the 2 barrel carb on that motor with it. It doesn't have any brand name on it anywhere so I assume that it's a factory intake.
I sold the motor last year & can't use it now. Can you help me identify it since I never installed it? I would like to sell it & don't want to misrepresent it. It has the casting number " 25512236 " & has a " T " cast on it near the water neck. It has facility for an EGR valve on it. I'll try to attach a photo also.
Thanks.........Odie
