I have two 4bbl N94 air cleaners (one water drain & two water drains), the NOS unit Tom (in TX) & Ken Mosier used to own has the 340 part number and one drain
there is a different part number for the 383/440 4bbl base, but I have never seen one & do NOT know what it looks like ( is it as simple as one drain VS. two ?? ) shruggy
