Default ??? Carburators On 502

Hopefully an easy question for you knowledgeable motor guys. I have a couple carbs from my original 93' Merc 502's. I looked at the Carbs can't find any info or Manufacturer or part number. Does anyone know what type of carbs these are. I want to list them for sale but want to describe them acurately.

Don't know if Merc would have used more than one type back then.

Thanks in advance for any help.

Aren't the most common carbs on these motors the 750 cfm Rochester Quadrajet carb?

I remember my old boat 93 Challenger with twin 454's came with Carter I am pretty sure. It was years ago and I didn't have them on long so am not 100% sure however I know they were not Q-jets.

if they were rochester the secondarys would be 2 1/2 x the size of the primaries throttle blades...Weber,carter,edelbrock are all the same castings by weber and you would see Weber's name casted into it..holley would have 2 fuel inlets on the choke side of the carburetors,weber and q-jet would have one fuel inlet..
