It all sounds very hopeful. If you ensure that the second 'phone is wired up the same as the first, then connect the two together (L1 to L1 and L2 to L2) operating the magneto on one should cause both sets of bells to ring.

If that is OK, I suggest connecting one or more 1½V cells to the battery terminals of each 'phone and see whether sound into one transmitter (microphone) can be heard in the receiver (earpiece) of the other. If so, congratulations, you have a working system.
