Dear Mr. Smith, Thank you for your letter of the 21st. We send you herewith drawings of the gear wheels we hope you will cyanide harden for us. The "G" numbers are gearbox gears, and the "E" numbers engine timing gears. Perhaps you will let us know whether any of these will need any grinding after heat treatment. Yours sincerely, | ||
