Help with determining musket lockplate

[Hérésie]

Hi all,

I would like to ask your help identifying a brass lockplate, probably of around 1600. I have spent many hours looking for parallells, but I do not manage to find out.

The first picture shows my own piece; the second picture is from the Guns Wikia page, but there no additional information other than 'snapping matchlock' is indicated.

Does any of you recognize this piece, and in first instance which type of lock it is?

Any help would be much appreciated!

Happy newyear!
