That's an unusual letter in the design number. If the "T" is actually an "L" then it's probably from a Funk B 75 L, and quite likely manufactured by Sensenich, as that is consistent with their serial numbering between 1932 and 1942..
If not, I don't know what it's from. Usually the middle letter indicates an engine hub type, in this case "L" would be for Lycoming. I'm just not aware of "T" even being used in that system of designation.
