That would help us sort out what is possibly going on.

Agreed. I am unaware of any Pentax flash model called "Xtra" and am also unfamiliar with a line of flash that goes by that name.
Fast forward ten minutes: I found a reference from 2007 on the Pentax User Web forum to an inexpensive low-power slave units sold by SRS under the name "Xtra". Searching further led to references and photos of a Pentax-branded unit called "Xtraflash" and finally, I found an old "sold" item listing on the marketplace here on Pentax Forums.

Forum user @shaolen was the seller and also the OP for this thread. I guess that makes them the resident expert on these units.
