@Daryl, Braddell is a going concern for general sporting goods. Web site says that most of their records were lost in a fire at the Castle Place building, but I have an email in with them. I've read that the current business doesn't much care for these sorts of questions, though.

@Fletchedpair, Braddell themselves mention that Charles owned the business (http://www.braddells.co.uk/about.htm), so making his home in Belfast seems right - or are you curious which came first, buying the business or making the family? That would be a good story.

@Hugh, I'm not brave enough to turn the screws but will ask whoever ends up servicing it for pics and follow up.
