I tied these two patterns, 1/2 dozen of each for a fly shop – customer – where I have previously taught fly tying classes. They were sold to Fishing Creek Angler in Benton, Pennsylvania. The shop owner told me they are for a customer in Scotland Yard. The hooks are Mustad 3399 size #8. The dressing for the Lady Gray normally calls for a tail of barred wood duck, but the customer specified yellow.
