John, I know that the Suomi MPs used both a 32 round stick mag and a 71 rd drum. I have been told that there was both a smaller drum (40 round I think)and a smaller stick mag. I wonder if the stick was a 24 round mag?
The pencil date on the box appears, even under a glass, to be under the wax sealing on the outside of the packet, In fact, under a glass the writing is a bit more extensive than in my original post. It seems to read:
27 3T ↓ƒK
This is a very rough representation of letters that are hard to read. In addition the last letter in “27 3T” is partially wrapped to the top of the packet and most the the following letters on the same line are also wrapped to the top of the packet. The fact that these letters wrap around the corner of the packet indicate that they were written on the paper before it was wrapped around the packet.
Also note the sealed end of the packet which has a pull string.
The was seal and the pencil marked paper could have been added later to an original Geco packing.
It is clear that Geco was selling ammunition to Romania (and perhaps) others in 1944. The two boxes illustrated below are clear proof. Both were obtained full.
The first containes Brass case cartridges headstamped C M C 9L. The loads have black casemouth seals, and nonmagnetic GM bullets!!! Note that the label is dated 1944. The blue box visible below the label is clearly a Geco box. in fact the second photo below shows the side of this box and the side of a Geco box that contained pre-1946 Geco headstamped commercial ammunition.
The second box has a Romanian label but a Geco end label. The cartridges in the box are lacquered steel case loads with GM color mE bullets. The headstamp is dnh St+ 6 44, only four lots earlier than the box at the top of this thread. Clearly Geco was actively making ammunition for other than the German Army very late in the war. Perhaps the 24 round box is another example of this commercial activity.
