This contribution allows you to quickly identify products which use identical model names, so you can fix them and have unique model names across your catalog.

QBI is an example of a Zen Cart plugin which requires unique model numbers. If you have duplicates, you will get an error like this:

Warning: You have duplicate Product Models! Models must be unique! Correct this issue before creating iif files!

Find Duplicate Models creates a new menu item in your admin (accessed by Admin > Tools > Find Duplicate Models) which shows a single screen listing all items with duplicated model numbers. The screen looks like this:

Zen Cart Find Duplicate Models screen

The "Model Number" field is a link to the product editing page, which allows you to quickly fix the model number.
