SEMPERFLI Chadwick 477 Substitute

Product details

Chadwick 477 Substitute is the perfect wool for the Killer bug classic Grayling pattern designed by the legendary Frank Sawyer.

This fly pattern is still very productive, but according to Sawyer’s tying instruction, the Killer bug should only be tied with Chadwick’s No 477 wool.

Semperfli has a card of the original Chadwicks 477 which was used to create a blend of wools to match the developped substitute. This is one of the most accurate Chadwicks 477 substitutes available. The Killer bug pattern is one of the most deadly and simple flies ever tied!
