I only know that Dr. Frank used FLCY-types in his Fluke 752-replica -> https://www.eevblog.com/forum/testgear/hp34401-measurement-of-linearity/msg358713/#msg358713
"I used 104 identical metal foil resistors, FLCY from Alpha Electronics, 25kOhm, 0.1%, 0.14ppm/K typ. @ RT, available from rhopoint components Germany."
Dont know if anyone used TLA/TLC though.

I used the FLCY, as they were available from stock, with appropriate standard values (i.e. 120 Ohm, 1k, 12k, 13k, 70k) for the LTZ1000 circuit, and for a reasonable price,  compared to the original Vishay BMF resistors. rhopoint components in GB had / have them in stock.
Made good experience, as these parts seem to have less variance in T.C. specification than Vishay, see also Andreas analysis on these components.
That was important for the build of the Hammon divider, as it lives from equal T.C. of its 100 constituents.
