X 8436 We are sending you a sample silencer from the Aymard Co., of Ipswich. This is said to have the following advantages:- 1. A clear passage to its entire length. 2. An impossibility of its becoming choked. 3. Ease of cleaning. 4. Entire absence of back pressure. Perhaps we should be able to see how it can be fixed if you had it unpacked.
