Canon LTM body serial number question

[Charles S]

Recently bought a Canon II series camera.
I am having difficulty identifying which version it is.
Serial number is 19XXX
Was wondering if anyone has an overview of the serial numbers by body type ? Google didn't help me on this one.
Thanks,
Charles

According to Peter Dechert's book of Canon RF cameras, that number falls in the range of the S-II, which has a range of 15700 to 23375. According to the book, slow dial shutter speeds are 1, 2, 4, 8 and 20, while high speed dial is B, 20, 30, 40, 60, 100, 200 and 500. The camera should have a combined finder.
