Dy{F R Danby} 12/P/34410 Newill, please receive copy of letter of the 20th-10 from The Hoffman Manufacturing Company Inc, with reference to special aero bearings you will notice that they have not any catalogue for us dealing with lighter bearings at present. They appear to have had some special types which however since they are not keen to make special sizes at this time, they will not give any information of these. sgd FG. | ||
