I'm venturing into a new field for a pal. It's a Bakelite factory slave clock with a 12" dia. dial. I'm guessing 1950's. The Bakelite is a bit grubby but is responding to some Farecla G6 finishing compound. Glass is just a wee bit scratched.

Guess a quartz fitment is needed, but I've never removed big hands off their spigots before and need advice as to sourcing the correct battery mechanism replacement, please.

Regards, David.
