Made to fit the Fiala models FM60 and FM 70 motors
These are made by Tony Clark models they are a ready-made stainless steel header with 10 cm flexible tubing, designed for Practical scale big Tiger Moth but can be used in other models. The tubing can be cut to length if necessary. The header is attached to the silencer (Zimmerman part 7670 or 7675) by screwing it counterclockwise and tightened, by turning it clockwise. The flexible tubing is wrapped like a spiral spring and as a result the diameter can be adjusted.
