That's odd.... I wouldn't have expected the induction coil to be on the bell set chassis. In a normal 232 it's in the main part of the telephone.

I have a couple of Telephone 232's with the Bell Set 26 screwed on the bottom. They are a normal 232, a normal Bell Set 26 and a short 3 core cable to link them. There are 3 N diagrams that apply :

N332 for the Telephone 232
N526 for the Bell Set 26
N4300 for how to connect them.

I would start with those and see if you can relate them to your telephone (which will be different).

Incidentally, the wires on the back of the dial go in the order Blue, Slate (grey), Brown, Pink, Orange. That is the case in every ex-GPO telephone I've ever worked on, and even some Australian, etc, ones. I was taught the nmemonic : 'Bill Said B****r (the) Post Office' to remember this.
