Thanks KevinH and Chopin, I accidentally posted the Lundberg. I will rub some talc on the etching of the LCT and repost pictures. One one you can clearly see that the bottom finish is a different color than the entire piece, as if sanded down. Another has sharp edges around the pontil deeper that I believe it should be. One also have various levels of the bottom and pontil, appearing to also been ground or sanded down then marked with the LC Tiffany.
Ok tried the Talc, but not much better. Two have just the L.T.C etched, one has LCT H763, two has L.C.T. Favrile or Famille? Really need to find an appraiser near me to visually inspect them.
