Would you tell us what we should check? Is it ok to check the model/mode number? Do not you have the copy of the model/mode number for the delivered item? If you have the copy, you will probably see what you sent.
What do I have to search? Type of its parts? Type number? Don't you have the type of the item to be delivered and copy of the type number? If you have the copy, I can see what you had sent.
