The D.R.G.M.s seem a bit loose as far as dating. So without an actual copy it is difficult to tell. The originals were probably lost during the war.

130844 - 2.24.1900
152004 - 3.23.1901
152292 - 3.29.1901
121257 - 12.15.1901

They were in effect for 6 years. Assuming that D.R.G.M. 130243 was issued in early 1900 then the number would be used for at least 6 years and then it would have been issued a serial number in 1907 or 1908. I'll look at Jeff Stephen's list in DGJ in 2004.
