When Faggin designed the MCS-4 family, he also christened the chips with distinct names: 4001, 4002, 4003, and 4004, breaking away from the numbering scheme used by Intel at that time which would have required the names 1302, 1105, 1507, and 1202 respectively. Had he followed Intel's number sequence, the idea that the chips were part of a family of components intended to work seamlessly together would have been lost.  Intel's early numbering scheme for integrated circuits used a four-digit number for each component. The first digit indicated the process technology used, the second digit indicated the generic function, and the last two digits of the number were used to indicate the sequential number in the development of the component. The 8008 microprocessor was originally called 1201, per Intel’s naming conventions. Before its market introduction, the 1201 was renamed 8008, following the new naming convention started with the 4001/2/3/4.
FH Grubb Ltd folded in May 1951. Holdsworth immediately bought the marque and stock, but decided to use a recently adopted form of his name on their bikes Freddie Grubb the first one was brazed up by Bill Hurlow very late in 1951 or early 1952 . Bill says late 1951/ early 1952 business at Holdsworth was so slow they used to wait for the mail to be opened to see if they had frames to build. They used plain gauge tubing on Freddie Grubbs, they were aimed at the "Winter Bike" market. Bill left just after Easter 1952. Stan Butcher, the WF Holdsworth wartime shop manager, joined Holdsworthy about then.
