Yes, it does appear to be the later type barrel insert, with an "extra" short spacer that would/could allow the unit to be used in a 6" barreled luger.

It is not a period piece of the kit; but useful.

I made one for my kit and have used it in a 6" "navy" shooter. Works fine, and actually looks better when installed.
