choke tower reads " LIST -3310-1" and under that is "1293" im told the 1293 is the date code and 4 digit date code wasn't used until 1973. I see no OEM manufacture type numbers. I was trying to find out if this was a desirable carb with an OEM application but doesn't look like by the numbers im coming up with. Looks to be a universal 750 vac secondarys.
Someone told you wrong. This is a picture of my oem 69 a12 carb with a 4 digit code of 0729. That could be a bowl from a mid 70 six pack. I’ve got lots of them. That has a newer plastic vacuum secondary cover.
