Harrach Marmor Aquamarin/Muhlhaus (possibly) Vase and Bowl set - with Chickens!

I saw this little vase and bowl set and fell in love. We are animal lovers, and in addition to our three cats and a seven week old puppy, we have seven bantam hens who free-range in our back garden and provide us with delicious eggs. I don't have many chicken-themed items around the house, but these were just so unusual - "Mary Gregory" style chickens! :)

I have identified this set as Harrach, in the Marmor Aquamarin decor. (The bowl is marked with a 19. in gold script, and the vase with an 11.) It is a beautiful clear bright blue. Alisa was kind enough to take a look at the pictures for me, and pointed out that they were probably decorated by Muhlhaus in Haida, who primarily worked on Harrach blanks. However, in further discussion within a Facebook glass group, it was thought that these may be by another company, and decorated in the style of Muhlhaus. I was shown an amazing example of decoration by Julius Muhlahus that had much finer layered enamel work than on my pair. It was also discussed that companies often had their own varying qualities of decoration from very fine to more rough, so these could be a less refined example by Muhlhaus.

I believe these date to about 1885 - they are in just about perfect condition, which is amazing to me. The vase with the hen is 5 1/2" tall, and the bowl with the rooster is 2 1/4" tall x 3 1/2" in diameter.
