Help Identifying Collets

[Ben17484]

I’ve a set of collets (and holder) and I’m not sure what type they are. They’re definitely not ER, and the dimensions I’ve taken don’t match anything I can find online:

Can anyone help identify them?

Thanks for the link, but none of those seem to match mine.

I’ve still no luck with this. There must be info out there somewhere, I just can’t find it.
