The "phono" at the lower end of the dial is their version of a shorting switch. The phono input is likely always live, and many sets of the era used the tuner as a mute circuit (at fully meshed, the rotor and stator plates short together, killing RF signal input, so you can listen to the phono without noise in the background.)

Brenda is no doubt correct although there are other ways that Phono position can work. On the Fada I'm working on there is a reed switch which is triggered by a tab when the dial is in the phono position. When turned to phono, a tab on the dial triggers the reed switch to open the input to the volume pot from the RF section and connect it to the phono input. If that makes sense? Neat the creativity back in 1929. On the Fada, the phono input is only live when in that position.
