Weird elevator arrangement: 1956 and 2013 elevators at Finke-Hochhaus Bremen, Germany

This building has been built in 1956 and features two elevators. One of them has been replaced by a new OTIS Gen2 while the other one, a Joh. Holtz elevator, still looks very old fashioned. The old elevator only goes between ground and floor 8 and skips floors 1-4.
