What Type SMKH do you think this is? sealed 300 Rounds

[Mlea]

Does anyone have any idea what type this might be in this sealed pack? I can see a bit into it as it has a small rip in the box. It has no iL mark on the boxes as well. Most I have seen for sale or around have the iL mark. I’m guessing everyone is going to say I should break this one open. Thanks for the information and help. The box also has a 1937 stamp in it you can see a bit in the picture

Thank you. You saw every type and markings as you unpacked and sorted it all. I’m torn on opening it up or not. I’m hoping your next lot has some interesting and rare stuff. It’s hard being patient and not spending my gun money waiting.
