Here are a couple of early targets in the 32-20 serial number series.
This first one is 32-20:
Now - this next one is actually chambered in 32 Long, but serial-
numbered in the 32-20 series. I regard this gun as the first K-32
target revolver. Serial-numbering it in the 32-20 series makes more
sense than in the 38 series, because the barrel caliber is the same as
the 32-20.
