PEREGRINE GEAR RATTLES.

We have had considerable success in eliminating rattles with the damper to Hs.{Lord Ernest Hives - Chair}750. We now want to find out the minimum inertia with which it will work.

Will you please make for us a further pair of flywheels to Hs.{Lord Ernest Hives - Chair}966 as soon as possible so that we can complete our tests. If it would be quicker to make them in S/M or I/C, either would be suitable for a test.
