Ok...I tried to crack the code...to no avail.
I don't get it. There must be some rhyme to the reason...after all, it's their corporate logo!
Even on their website and corporate literature...the ampersand is cut-off.
I have 7 pieces that I've checked on:
1. Lange Perpetual...round top...straight logo
2. Lange Datograph...cut off top...curved logo
3. Lange Anniversary...cut off top...straight logo
4. Langematik w/ date...round top...straight logo
5. Lange Cabaret...round top...straight logo
6. Lange 1815 up/down WL LE...cut off top...curved logo
7. Lange One...cut off top...curved logo
And...on the back of every one...round top.
So...I'm clueless on this one.
Craig...what's the theory???
