I have these bym Genossenschaft Maschinenhaus, Ferlach-Kärnten, Österreich from 1941, 43, 44 and 2 from 45. These bym from 1944 and the 2 skeletons from 45 were found on Lake Ossiacher in southern Österreich back in the 70s. bym from 1941, 43 and 1944 are all matching numbers, bym from 1941 and 43 each have their own Tropical frog.

bym43 WaA939 - With 8 numbers 83123 416
bym4 WaA939 - E-block 4560E
bym5 is stamped with WaA938 and means that it is approved for bajonet/blank weapon at Wehrmacht.

Ferlach used a unique numbering system for their bajonets from 1939 until midway through 1944. It had a two part number (i.e. 83158 over 416) with the first number being a bajonet serial number. The second number was the batch or series number and was stamped below the actual serial number and changed every 200 numbers. For the example number provided, if you multiply 416 x 200, it indicated that this bayonet was piece number 83,158 out of a batch or series of 83,200 bayonets. In late 1943 (suffix blocks A-C), they changed to the standard 4-digit number w/letter suffix system like all the other makers.
