Carb numbers

Can anyone help me decipher the meaning of these numbers? Is it an Oldsmobile carb? Build date or mfg date I know it is Rochester 2bbl, but I don't know if it is original to my 1972 Cutlass Supreme with a 350. The vin says it is a 2bbl system from the plant in Arlington, Tx.

I plugged that number into a search engine and it came back with hits for a 1972 Oldsmobile 350-2bbl.

It is CORRECT for a 1972 Olds 350 2bbl motor. There is no way to know if it is ORIGINAL that came from the factory on that particular motor, since carbs don't have VIN derivative stamps that match the car's VIN and thus can never be "numbers matching".
