They’re in Bishop, California doing a currently small WFNA/something
hypergolic rocket motor
I did a little sleuthing off their website. Here they mention
consultation with friends at Interorbital (para 9):

Now over at the Interorbital website, they mention their Neptune rocket
which is powered by WFNA and turpentine.
Here para-4:

I doubt that the information about Interorbital is news to the regulars
here.
Also see the video above at 01:52 one of the team opening pressure
values on what I would presume are nitrogen tanks, with the silver
(stainless steel?) tanks behind them presumably containing fuel and
oxidizer. There is also a point in the video at 2:03 showing a team
member adding what I presume is a reactant from a step ladder to an
opening at the top of the trailer. Note also from the 01:52 video still,
the feed lines running from the roof of the trailer into the silver
tanks. Since nitrogen valves are also mentioned in the video. So I'm
willing to make a (small) wager that they are using a pressure fed GN2
with WFNA/Turpentine engine.
As per lack of shock diamonds, they mention that in the above link in
para 13.
So George, I hope you are able to reach them sooner rather than later.
