| 4. What position would the valve take up on either the type of thermostat which we have tried, or on B.G.A.3357.A. thermostat, if the bellows punctured.? 5. What provision is made on B.G.A. 3357.A. thermostat for allowing air to leak past when filling system with water. 6. Are you prepared to supply us with thermostat bellows to our drawing EB.667 (attached) as a production proposition until such time as we are in a position to standardise one of the types of thermostat discussed above, and what would be the production price of such units (to EB.667) An early reply to these queries would be appreciated. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
