Journeymen, one company that made these, both under their name and for the trade, was Greifelt. Here's a link to one of their German catalogs where pics will be found on pages 13 and 15.

The actions were made both with (as in that link) and without the side shoulder panels (as in yours). Here's another link to a very similar one marketed as an "Ideal". Here's a thread that has both with discussions:

In Frank De Haas's Single Shot Rifles and Actions he called it a Kettner, for lack of an actual maker's name, as that was the name on the barrel of the shop that had marketed it. It is a late and very strong action. It's possible that it is not, per se, a 22 Hornet but the German version called the 5.6x35R.
