Quoted from avspin:I'm going through the blueprints and drawings and they each have a game number on them. It's a pain searching IPDB for find the game for each number.
So I created a chart that can be sorted on my website. Not everything is there yet, I'm adding them slowly but it's over 250.
I'm sure others can use this chart for reference.

Do you use IPDB Advanced Search? You can enter a model number and pull up the game associated with it. I notice your list is all Williams. Using Advanced Search, I can select Williams and select to sort by Model Number to pull up our entire list:

I get 554 hits. But maybe that's tied to my supercookie as the Editor. How many games do you pull up using the above link?
Is is useful? Or, I could be missing your point entirely. If so, then.. sorry!
