These are the kits that I am aware of that used the two tube sizes in question. Note that the BT-58 was originally created to use for Service Module in 1:100 scale Saturn IB/Saturn V kits. ST-11 (FSI HRT-10/RT-10) was originally used by Flight Systems, Inc. as a motor tube for their E60/F7/F100(F80) motors. IIRC, the only other kit manufacturer that used that size was Semroc in their 2000s incarnation. CMR (Competition Model Rockets) used a similar size for rocket that used the 27mm FSI motors.
