Mystery small Flintlock

[Watauga]

Mystery small Flintlock   I picked up this small Flintlock at a Pow Wow... it was rusty wouldn't spark and barely moved because of all the rust... and the Mainspring was in it wrong .... but for $15.00 I bought it   It looked a lot like the lock in my Pedersoli Kentucky pistol. And I was hoping it would swap out with the Cap lock pistol and I could switch from flint to cap whenever needed.... but it somewhat fit the mortise but the lack bolts are closer together and the part that holds the frizzen will not fit in the mortice...     Anyway I have this lock and now it sparks good If anyone knows what it fits it would help me track down something to put it in The mainspring has the "stirrup" and 2 hook deal like the Pedersoli Kentucky lock...  and no made in marked on it anyplace... 4 1/4 inch lock-plate length  1 1/4 inch wide from the top of the pan to the bottom of the plate +/-         Thanks in advance if you can help me out!
