Wipac was an English company with some kind of relationship with Wico, probably initially a licensing agreement. The magneto on the Hurricane in the picture was made by Wico Electric Company. Here is a blow-up of the center of Ty's pic:

The part number is Y12182, which is a Wico part number. I can't read most of the words on the pic - Ty, you should be ashamed, not one of your usual prize-winning pics - but it seems like a Massachusetts product from the company name and the part number, plus I think I see "MASS." in the third line of text (can't read the name of the town though - WICO was originally in West Springfield, MASS).

Slightly off-topic, you can buy Wico's original certificate of incorporation, back when it was called Witherbee Igniter Co, if you want to (and read the company history at the same time):
