German Letter Opener

Hello there, I came across this letter opener from Germany. It’s hall marked Germany with what appears to be a crouching lion over the letter “E”. There is an ornate design on the handle and I suspect it is war era? Any info would be greatly appreciated! TIA!

I’m sure that the use of the word “Germany” can be used to date this approximately. After WW2 I assume we would expect to see “West Germany” so I guess this must be pre-war. It looks like brass so the mark is not a hallmark, merely a manufacturer’s mark.
