Smog Pump Numbers?

[hiperf69]

Hi bill, what is the stamp date on the side of the pump?
The cast ( jullien) date looks to be 22nd or 220th day of the year it was cast.
Stamp date on side will be a pretty close date but must be stamped after that cast date.
Sample;
22 cast date would go good with a 0349 or Feb.3rd of 1969 and so on.
Also there is a cast calendar on the front face if you have to pull the fan.
Hope this helps,
Joe
