Yup, your description is like mine except it isn’t able to be disassembled. Thanks.Mine resembled yours, or maybe the other one. Either way the shape was identical and it was a Schrader. It's been half a century since I've seen it. I remember it had a hex head, the thick bit between the two halves and a flat gauge rod. I vaguely remember being able to disassemble it.
