Your pot was made by Heubach Brothers (Lichte Porcelain Factory). The company was renamed Lichte Porcelain Factory after 1948 and reduced to Lichte Porcelain GmBh in 1994. The phrases that Replacements use will not help anywhere else on the web because LFE3 is a control that the website created themselves and was not created by the porcelain company. If you could please add pictures of the pot and of the marks on the bottom, I can get so much more information from a visual. Add pictures by using the Add Files feature on your screen. I will get an email and finish my answer once you have added these.
I am following up to see if you were able to get pictures of the pot so that I can finish helping you?
