Appendix:
Battery Details.

This battery is no longer produced. The only source I have found is Small Battery Company, built to order if you really need one of these.

I found a reference to the fact that 2 × 455 in series can replace this battery, there should be enough space, but you will need to fabricate a jumper wire to join them together. This can easily be done by purchasing a pair of snap terminals and joining the wires together.
