How about mangled upper case?

Okay, some fonts are a bit less conventional than others. And when you're reviving old typefaces you can run into some strange characters (pun intended, of course). This time I came across two weird versions of the upper case "R'. The first was seen on an old dairy factory, in Dutch "ZUIVELFABRIEK DE SOESTER".



The "S" is very intriguing, but what about the "P with an extra stroke"? This should be an "R"?

Example number 2 is to be found in Amsterdam, on the front of an old pharmacy. The text reads "DE RUYTER APOTHEEK", but see for yourself:



This is a "D" with an extra stroke, to turn it into an "R". Should I stick to the original, or should I tweak the R a bit? In other words: would you be confused, reading the original lettering or not?
