Full Title

Full titles differ between systems:

IPC:

Control systems or devices for copying directly from a pattern or a master model; Devices for use in copying manually > using a feeler or the like travelling along the outline of the pattern, model or drawing; Feelers, patterns, or models therefor > Feelers; Feeler units > designed for physical contact with a pattern or a model > for control of an electrical or electro-hydraulic copying system

CPC:

Control systems or devices for copying directly from a pattern or a master model; Devices for use in copying manually > using a feeler or the like travelling along the outline of the pattern, model or drawing; Feelers, patterns, or models therefor > Feelers; Feeler units > designed for a physical contact with a pattern or a model > for control of an electrical or electro-hydraulic copying system

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
