RE SILENCERS.
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.
