FENTON Crimson Glass Apple? I am going with PLUM. Sticker intact

Vintage FENTON Crimson Glass Apple. That is what I have always heard this referenced as, but I am going with a plum. It looks exactly like the fresh plums off my plum tree, and nothing like any apple I have. The color is just beautiful, but again, appears to me to be more like a plum. Please see photos, I may just be going color blind...Excellent preloved Vintage Condition. No chips or cracks. Sticker intact. Gorgeous color!
