Me neither! Looking at the "paster" diagram, all it seems to do is short out a 0.8μF capacitor that, along with a 2μF one is in series between the handset and the line - effectively reducing from 2.8μF to 2.0. The Mk II doesn't have this switch - or at least mine doesn't.

One of the other members of his group has one of these, http://3.bp.blogspot.com/_k07pirzBU3...00/DR8RL39.JPG so they are almost there to connecting up to another group during one of their re-enactments.

So, you have one telephone and a reel of cable. You just need something to attach on the other end.

For interest, I attach below images of my two telephone sets "H".
