On the one barrel carbs the number is either in the base, or sometimes into the side of the float bowl. Not up at the air horn area as common with others. It also may NOT have List # in front of the model number. Could be a R-xxxx or simply w/o any prefix.
Now, you sure too that it is a Genuine Holley? There are some look-alikes out there.
The number 4694 comes up to be a replacement carb for Ford 170 and 200 of the era 1962 through 1969. Seems to be a generic type, once sold over the counter of some discount auto parts store. Was auto choke instead of the manual like used on round body Falcons.
It is one of the "family" of 1940 types, but different none the same.
No they don't. Only the very early type 1909 had the glass bowls. There were several varieties of this carb. used for years. Read your Holley manual and will see that later on they were all converted over to metal bowls. Was a ruling that broken glass bowls when broken via accident contributed to fire under the hood. If the carb went off to a professional rebuilding place, they would automatically replace the glass with the metal type because of such ruling. To find a glass bowl carb. is to find one that haddn't been to a rebuilding plant.
