It looks like you have the network parts (induction coil and condenser). Try Steve Hilsz for the ringer. Gary Goff sells replacement rubber gaskets, I believe. If you are going to use a WE #4 or #5 dial, the dial contacts which open when the dial leaves the rest position are wired in series with the receiver. With the AE dial, the shunting contacts are wired in parallel with the receiver. If you want an AE dial, keep looking on ebay. They can frequently be had for less than $20.
