Got it on my take down Jaeger rifle and it functions well.
Historical accuracy is hard to tell, depending on what time period this lock is from or if the form of the lockplate was altered for production.
I only partly agree with Ron as to past 1730ies, this lock bananas a bit too much and is generally too large.
But 1690-1720 the locks appear to be bending down somewhat more. They also tend to be mostly round faced earlier, at least from what rifles are still on the market from back then.
But without knowing the rifle the castings came from and the date of the rifle, it is extremely hard to tell.
I agree though, that it is not appropriate for some of the Jaeger rifles, especially American Revolution period rifles.
