My wife just remembered the place she bought it from, a store called Lionheart. I'm guessing the lion-like image is that of the store maker mark, and that also makes sense for the Lh letters.

Ah, sorry!

I have a feeling they could perhaps be decorative hallmarks.

Hi,

My apologies:

Hi there, My wife bought this in Japan about 20 years ago, but I don't think the hallmarks are Japanese. https://www.dropbox.com/s/z2lkimpxfiimizc/20191115_165741.jpg?dl=0 https://www.dropbox.com/s/1lzw1r1yg7p4ie1/20191115_164208.jpg?dl=0 https://www.dropbox.com/s/8c27dvvc0ocslfe/20191115_164155.jpg...
