Vintage European soft paste vase makers mark unknown

Unknown makers mark soft paste vintage vase matte glaze on exterior gloss glaze on interior vase has a flat front and back middle has flowers with gold highlights. The base and neck look like a tree trunk design. The makers mark is stamped on top the glaze and is a circle with crown on top, smaller circle inside with the letter T inside, I can't make out the lettering. The numbers 468 are scribed in the bottom and written on one foot. 7 1/2" tall x 4" wide x 1 1/2" deep. I am trying to identify the maker. Has anyone seen this mark?
