I'm having a tough time with a pair of cufflinks. I suspect these are Danish based solely on the design-- could be totally off base here. I can't get anything out of either of the hallmarks. I hope that perhaps they will ring a bell for someone. Many thanks for your consideration.
Hi, Not Danish but Dutch, silver-plated and made by; Herbert Hooijkaas or better: Fa.(Firm) H. Hooijkaas 1874-2008; Zilverfabriek Schoonhoven. See: http://www.925-1000.com/silverplate_H3.html
