Very commonly used before the metric fuses became popular in the US.
Converted to metric it would be a 6.35mm x 32mm.

The "AG" means auto glass. These were typical in American cars years ago before the blade type now used.
You can easily order them on Amazon. As an example, here's a 3 amp Littelfuse 3AG Slow Blow.
Make sure you look at the current rating stamped on the end of your old fuse.
