I was searching for information on this topic and found this thread. I also managed to find the old Jouster thread. The above list is missing a bit of information. Here is what was on the original date list, cut and pasted:

My little DWM 1891 carbine is serial number C05XX, which would put its manufaturing date as sometime in 1899.
