C clefs as Ks

[kfey]

Greetings!

I'm looking for as many examples as possible (cc. violists, trombonists, cellists, bassoonists, etc.) of C clefs that look more like the letter K than the typical B or even H/whatever this is.

Good examples are in some late 19th-century editions by London publisher Novello. Take this one, for instance.

Any others publishers you may be aware of? Or some info on where this was common practice? I seem to recall the K was popular in France around the same era as above, but I'm struggling to find examples.

Thanks in advance.
