The Impossibility of Double Gallows

[Koen G]

To be honest, I'm not sure yet myself. Certain elements in my label readings point to the fact that at least the gallows "K" and "T" are a more ornate way to express sounds that are also expressed in bench ligatures. I say capitals because upper case letters is the closest resemblance we have to what I envision. They are used word-initially (ignoring prefixes) or in a number of other scenarios, for example to draw attention to a certain sound. We could also use an upper case letter there, like "it's iMpatient, not iNpatient."  I haven't read nearly enough labels yet to be sure about this though.

But if  this is true, it may not be totally unlikely that the gallows you describe are just extra ornate versions. But these don't appear in the labels I'm studying, so that's pure speculation.
