I have a customer who wants me to order a couple replacement parts for her mother. First off, she needs a protective cover for her crinkle cutter. She has an old one and the blade is flat, it doesn't rock. Is that just the old version crinkle cutter or is that an even older style? I know that the current one and the old one are on the replacement parts order form, but I wanted to be sure there wasn't an even older version. Then she has an old A/P/C/S from at least 10 yrs ago. It has 2 different thickness blades (from what she's describing to me). One of the prongs broke off from the arm. I know that on the replacement order form it has the Three-Pronged Fork on there, but will it be compatible w/ this older version? Any help would be greatly appreciated!
