Have you tried replacements dot com?

Yes, very disappointing, it's like they never even heard of Solingen.

Etsy was better, they had quite a few Solingen patterns but none was exact match.

rost frie means stainless....as in "rust free" There is a lot of Solingen rost frie flatware listed on eBay....don't know it any is your pattern.....but have a look.

...and try the European eBays. If this pattern wasn't exported, you might need to go to the source!

(Solingen is where it was made. I assume Herm zur Nieden is the maker?)

Yes Herm may be short for Hermann. I've searched the German eBay and did find a maker by that name. I assume it translates roughly "Hermann the lower, or younger"
