Help with mark on Austrian spoons

[AllSeasons]

I recently acquired some Austrian spoons. The Diana head mark indicates that they are 800 silver from Vienna. However, I'm having trouble deciphering the other mark. Not sure if it's a maker's mark, or an export/import mark, or something entirely different. Any help would be appreciated. The images are below. Thank you in advance!

Hello!
This is a trade mark of Josef Carl Klinkosch. See here: https://www.925-1000.com/forum/viewtopic.php?p=212241

Thank you! Given that this silversmith was active from 1843 to 1886, and this Diana head was used from 1872 through 1922, that would date these spoons to circa 1880?
