'57 Bird Carb, what carb should be stock for the motor?

[Zoopie]

I have a Holley carb but it has no model number, need help deciphering the numbers I do have on the unit: 794, EDC-F, SR 1432 B, 12R 1836B (near stud mounting hole) 2080 (Rear metering block) 854 (front metering block), 1551 (list). The manifold is a ECZ 8425-B. Any clues for model and again, what was original carb?

Look for the model number on the front side of choke housing
