I am not explaining your language, although I read manuscripts from your area quite regularly and I have noted the many dialects.
The letter "y" is not written that way. Neither is "u" or "o".
Here are some examples of medieval "y". They do not look like the VMS character above:
I am trying to explain something about how medieval characters are written and I have never seen that character in a manuscript from your region, unless it is the letter "p" with a long leading serif and an open top. But if it is a "p", then it does not mean "and".
Show me a sentence from a 15th century manuscript in your dialect (or even if it's not your dialect, it's okay as long as it is from your region) that has that character. You can find it in Old English manuscripts, but not in 15th-century Bohemian/Tirolian/Bavarian manuscripts as the word "and" (if it is a long-serif "p", then you can sometimes find it, but usually it is not so narrow and usually the connecting part does not slant like that).
I have looked at hundreds, probably thousands of German manuscripts and even if it's written in German, many of them use the "et" symbol instead of the vernacular.
