GRE, Radio Shack, and Whistler - Source: http://wiki.radioreference.com/index.php/Programming_Your_Radio_Shack_Scanner
For years, GRE made scanners for Radio Shack with the Realistic or Radio Shack or Patrolman names on them. Only occasionally would RS stray and get a model from Uniden (e.g., Pro-2050). In 2013, GRE stopped producing scanners under their own brand or for Radio Shack. In 2014, Whistler purchased and started production on scanners using GRE's intellectual property. For now, they are the same as the previous GRE models, just with Whistler labels.
To add to the confusion, RS re-issued some of their scanners with new model numbers. You can use the table here to cross reference the various model numbers between the brands: http://wiki.radioreference.com/index.php/Programming_Your_Radio_Shack_Scanner
