The LEGO set number 66648 does not correspond to any specific set detailed in the LEGO catalog up to my last update in 2023. Its possible you may have a misprint or a misunderstanding regarding the set number. LEGO set numbers are unique identifiers used to distinguish one set from another, and they typically consist of 4-5 digits. Often, numbers that start with “66” or similar can be part of special collections, promotional items, or even exclusive sets tied to specific themes or events.
To help you better, could you provide more details about the set? For example, the theme (like City, Star Wars, Technic, etc.), the main features, or any distinctive elements that came with it? LEGO has a vast and diverse product line that includes licenses from popular franchises, original themes, and even limited edition sets, so any additional information could greatly assist in identifying the specific set youre inquiring about.
