This lure is easy to make, when they first came out they were $1.95 which was expensive for a one striper GI making 33.00 every 2 weeks .
My father in law and I came up with a way to make them fairly cheap back then. You take a Hildebrandt #1 inline spinner put the fly of your choice on it add 2 split shot to your line about 10 inches from the lure and it works like a charm. You can find the spinners on ebay just search for Hildebrandt #1 single blade spinner , some have 3 in a pack some have 2. You can get the fly just about any place.
