I have a customer who is trying to do an adjustment on a Professional Square Griddle. I don't have a receipt, show, Consultant or old catalogs to find a part number. I called HO and they can't find a part number. I am holding the item - it's our professional line, square griddle. But it has warped and scratched surface. Does anyone have old catalogs that would give me a part number? For PC items that are Lifetime, you would think they would give us access to a list that has old part numbers! Or at least give HO Customer Service the list. What a pain!!
