Spark Plugs Cross-reference chart?

Has anyone seen a cross-reference chart for spark plugs by manufacturer? If so I would like to get a copy. I found some NOS plugs at a swap meet over the weekend manufactured in Pa. and was just wandering if they would work in a Model A.
 
There's a fellow here on the "Barn" that has extensive knowledge of what you are
seeking. He's got a chart with plug info, heat data and all that good stuff. Unfortunately I don't remember, but if you can keep the thread alive, I'm sure he
will pop up and answer all of your questions. Your question is whether or not they
will work, but the question you should ask is whether or not they will work efficiently.
Just because the plug fits in the hole and the engine starts doesn't really tell the
REST OF THE STORY.
