Thank you for your question. The 1959-LF is not part of our Trinisic Collection but does match the line. The difference between the 1959LF and 9959-AR-DST is that the 9959-AR-DST is that the 9959-AR-DST does have a pull down sprayer assembly with MagnaTite docking. The 'LF in 1956LF indicates Lead Free. The 9959-AR-DST is also lead free, as well.
