Felix Potin crocks with patina are always a favourite find, and I found two! Probably because I visit so many brocantes! 
 
You have the choice of patinated or heavily patinated - both are unique due to their aging. 
 
The Patinated is a café au lait colour all over with one small rim chip on the right side and some larger chips to the base, shown, but overall in good condition. 
 
The Heavily Patinated is cappuchino colour all over but with the chocolate dusting on top! It has a darker mottled appearance and is too in good condition, with only minor nibbles on the base.
 
Both are marked on the base one FP the other just the F! The patinated pot is stamped Luneville.
 
They are both 5.5" tall.
