The 1850-1 is a universal application Holley replacement carb offered from 1967 - 1972 or thereabouts. It is still offered today as the 1850-4. It is Holley's number one selling carburetor and is rated at 600CFM. It is recommended for 289 - 350 CI engines.

The other number does not appear in any of my Holely books but it is certainly not a Ford carburetor number. A factory Ford Holley would have a number similar to C5AF 9510 - BU or perhaps C5AF - BU along with a Holley list number. See any numbers like that on this carb?
