'67 Carb

[Flowjoe]

I picked up this carb:

Which Colvin identifies as a as a 327/275 (or 295) AT w/AIR, 3rd type.  I'm assuming that this would indicate a CA emissions carb.

1st question:
Any idea of when the 3rd type was phased in?

The date reads  1420 which I am interpreting as 142nd day of 1970...am I in error here?

2nd question:

If that date is correct then is this a service carb?

Thanks

Yup - service replacement carb, date as you noted.

It's very clean so I wonder when it came off the self. (that's one I'll never know)  I know where it has been for the last year or so (in a box according to seller)
