It should be an AC PF-25.
When the assembly line installed that white,bottom script embossed filter on the vehicle,it was identical to yours,only with all black printed text.This is a very scarce filter and wasn't available OTC.
Yours sounds like the later over the counter white service filter w/double blue line & script,and a red AC ball.Some of these colored ones had the embossed bottom,(I think produced in Canada),and some did not.
Below is what Charley found on his unrestored survivor 70-Z with the later applied undercoating..
Here's what Greg Roberts,(Nova Research Project),had to add..
"I decided to try to make one of the assembly line style oil filters. First run was so so.I need to make another screen for bolder letters.I did not have measurements so the size was a best guess.I also need screen ink that does not set up as fast the current paint.It probably would have been faster to just make clear labels."
