They both have the same 490mH generator and they both weigh 8.3g.
The 155 has a line contact and the ML is micro line.
Both - output 5mV. DC 790. Impedance 3.2K.
Compliance is higher on the 155 - 16 @ 100Hz. Cu on your 160 stylus is 10 @ 100Hz. That's the same as a 150MLX which is 18 @10Hz.
The gold on the cantilever is a very thin layer, vapor deposited.
Nice cart.
