For years, the gigahertz-peaked-spectrum source CTD 93 (1607+267; a NLRG at z = 0.473) has been considered the prototypical compact double source. Previous VLBI maps at wavelengths between 18 and 6 cm showed two similar components separated by about 50 milliarcseconds. Neither component could be identified as a core. We have mapped the source with the VLBA at 2 cm to search for the core. Our new map shows that the northern component of the double is more compact and has a jet pointing towards the southern component. The southern component is an extended jet which is brightest at its southernmost tip. We identify the northern component as the core of the source. We discuss the radio morphology of CTD 93, particularly the similar spectrum of the components. Comparison of 18 cm VLBI data taken 19 years apart shows that any expansion velocity of the radio components is less than c.
