Vintage bagpipe case lock

[pipergm]

Hello -

I purchased an old set of bagpipes that were made in Edinburgh and that came in what I believe is the original wooden case. I haven't been able to determine when the pipes were made, but someone suggested that the lock, keys, and latches on the case might provide a clue for someone who's interested in historical locks. I've attached three pictures, and would greatly appreciate any help that you can provide as to when this case may have been made.

Thank you very much!
