TRIAC tooling spindle taper

[triac]

Hi, does anyone know how many styles of internal tapers were used on the Triac ?
I have seen BT35 and R8 mentioned, also in 1 thread ISO 30 is mentioned but not confirmed.
Also did all use the same pull stud type of draw in method, ie no draw bar.
Thanks in advance.

bt35 on the older 6 station autochanger version.

bt30 on the newer 8 station autochanger version.

r8 on old and newer non autochanger versions.

int30 on newer non autochanger versions.

old triac versions up to 90's (approx).

new triac versions from 90's (approx).
