The last thing you acquired, Lucky #13  

why
thank you!
I am really pleased to finally find one. I like the wheeled ver. quite a bit. Very serene.
EDIT - Is there some reason this is NOT marked HM? All the one's I have seen here on DA seem to have it somewhere? I guess if it was a label it could have fallen off...

Not All
Shells are marked HM - is there any sort of embossment? Sometimes you have to look pretty carefully...

I HAVE THIS TOO
I bought one of these in a thrift store in Pasadena, California recently. Yours is the first littermate I have seen online after weeks of searching. There must be a distinguished lineage, but mine has no marks, stamps, or other indications of origin. It looks like maple or birch. Nice dovetail joinery underneath. Yours looks in much better condition. Looks like a Swede but I'm no expert.
Curious about origin. Yours is the only other one I've seen. Found in Pasadena, California. Nice joinery underneath.
