Possibly Precision Tank and Equipment
Peoria Tractor and Equipment
I am wondering if it may be "Pacific Telephone & Electric Company". My reasoning is that it remindes me of "Pacific Gas & Electric" - PG&E, like seen in the movie "Erin Brokovich" with Julia Roberts. Is there any info where is was sold from?
power train and engine company
I am fairly certain that it is Peoria Tractor and Equipment Co.
