7.63 Mauser ID help

Can anybody give any information about these?
Thanks a lot!


The top one was made by Lignose A-G, Berlin, Germany. Prior to 1930’s.
The bottom one i can’t quite make out what the character is on the top. Is it an L as well or a 1?

I’ve never seen anything like #2. I’d start with China.

Thank you very much!And I think the mark on the bottom one might be a letter “L” or “□”
