Need help to identify collet holder please.

[Overland]

In a lot of BT 40 tooling I got.
The collet measures 2.405" long, 1.268" dia where it goes into the nut.
TG 100 seems to be 2.375" long, and 1.379" at same dia according to "Tools & Gismos".
So I guess not TG 100 collet.

The holder says: Valenite BT40-10SG-070
And the nut: VALENITE VCCNP 10SGF 9/30772/00.

Anybody recognize this please ?
Bob

TG100 would be my guess. The 9/16 TG100 collet I just grabbed at random is 2.395 long and 1.270 measured at the step in front of the retaining slot. It measures 1.38 at the largest diameter.
