Can you ID this shut off valve connection type?

[FVGomez]

I need to replace this shutoff valve with a dual outlet one. I want to make sure I buy the correct supply side type to avoid any issue when replacing. Can anyone ID this shut off valve connection type at the supply side? I do not think it is1/2" nominal (5/8" OD) because I don't see the hex nut to tighten it.

I am not expecting to find this decorative type 1/4 turn handle.
