According to the SLM roster, the locomotives were built in 1959 (works numbers 4323 - 4332/1959). According to the German wiki, locos were manufactured in 1962/3... What is true?

The SLM roster doesn't show delivery dates! The locomotives had been ordered in 1959 (EA 3/59) and wi can assume that SLM started work in this year.

They were put into commercial service in 1962 (16551-55) and 1963 (16556-60)
