Is there a model number visable anywhere on the receiver? As you might imagine, it's pretty hard to search using the word "Classic" but it might be easier to search for a "Classic ABC-123".

Do you have a guess as to the model year? If you were able to take a picture of it and post it, that might help too (just in case it's a re-brand, or maybe someone else has a model that's re-branded from the Classic).
