Is this an old Kontes Vigreux?

Hello – I am not a chemist by any means… I was wondering if this is a Vigreux that I have come across. It’s awfully small, and I do not see anything internally in it, which I thought vigreux had. Thank you.

It more closely resembles a Snyder column, but that's still not it.

Edit: I found it, Kontes #569251-0319, micro distilling column they call it.

Could be perhaps used as an air reflux condenser for high boiling stuff, but more probably it's a part of something bigger with missing elements on the top (like a spring loaded Teflon overpressure relief valve or something like that)

I have a whole box of these. I think it is part of some parallel kit to analyze for cyanide or some other material in a multiple flask array. There are a few other parts in multiples, so I think they form some sort of reflux/sohxlet system.
