Letters from the wall of Museum Koenig (in Germany)

Hi, This is from the interior walls a zoological museum in Germany, built in the first half of the 20th century, but the letters may be later. For an artistic intervention "answering" to this inscription, we need a font that comes as close as possible to this. The Q and R letters are quite distinct, as is the E. All the automatic font identifiers have failed so far, and I am at a loss here. Thank you!
