In my collection of English pocket watches I occasionally need to manufacture a brass part. Does anyone know of research that has determined the alloy of brass typically used for plates of these pocket watches? If there is little available, I may send some pieces to a lab to get an analysis.

This doesn't identify alloys but does examine the processes involved and a timeline. There was a lot of change during the 19th century, you may need to be more specific.

In the end I think analysis would be useful

I remember Oli cooke who is now Curator at the British Museum did some research into this when he was a student. May be worth dropping him a line to see whether there was anything definitive? As you say, testing would be a sure way of indicating composition although I think you will find there is quite a range of compositions. Cast yellow brass is quite readily available if you want to make parts that are at least the "right" colour.
