No luck on tag.. I looked all over that pump and couldn't find any numbers other than 0203. I guess when I get it home I will pull the pump and see if there is a tag on the bottom.
I came across a rather large compressor. It has a galvanized tank that is massive with a massive motor with dual belts. Single Phase motor. A lot of the markings are near impossible to read from what looks like paint over spray. I tried to rub off the paint and it tends to rub off the markings...
