Early dial variation?
Looking to learn more from Lange scholars...
I was perusing eBay the other day and came across this first generation 1815 U/D (221.021). It has a Certificate of Origin from Lange so I will assume that is in fact genuine. One thing that caught my eye was that the font was different and the Auf/Ab subdial is "connected" compared to my 221.021.The serial number on the eBay listing is 114xxx so it's quite an early one compared to my 140xxx.
I know dial variations aren't uncommon in the early years of Lange, so I'm curious if anyone know approx. when Lange made the update to the dial on these references?
Many thanks!

My 221.021 for reference:
