I really need suggestions on how to execute the below scenario.

So I have a tool history website that captures date codes, examples of tools, catalogs, etc. I've captured each catalog and catalog page in a taxonomy, which has a picture and a "tags" field. I input each model number on the catalog page into the tag field (OCR) which makes it very easy to rapidly search and find items in catalogs.

As I said, I also have tool examples, which have a "model" text field attribute that matches a model number somewhere in one or more catalogs / catalog pages. What I'd like to do is have a field on the tool example page that basically goes and retrieves the example in the catalog page(s).

My question is what would be the best way to do this? I really appreciate the help!
