Experimental Dept. Dear Sirs, We thank you for your letter of February 27th and are sorry our letter of Feb.24th, "JB/DH{D. Henderson - Showroom}/DOA" was not as clear as we intended it to be. The only dimension we wish you to modify is the unground recess diameter on F.89831. An increase on this diameter from 1.332" ± .005" to 1.338" ± .005" would save us an expensive form tool and expedite production. We feel perhaps you would like to re-consider your decision. Yours faithfully, THE HOFFMANN MANUFACTURING CO., LTD. | ||
