Ceiling fan hung on a 1x3 ceiling strip

I was replacing a ceiling fan...and ran into a surprise.

After removing the original fan, I saw a shallow pancake fan rated box. Initially I assumed this box must have been fastened to the bottom of a ceiling joist, but I removed the box to check, and what I saw was a 1x3 strip.

The roof trusses are spaced at 24 inches. The 1x3 ceiling strips, spaced at 16" are mounted under the 2X joists, perpendicular to the joists. Below that is a layer of rock lath about 1" thick.

The fan has been there for ages (from what the previous owner told me), and the new fan is about 28 pounds. I am trying to decide whether I can rely on this 1x3 to support the fan, it's not to code I know, the alternative is to cut a new hole where the ceiling strip isn't, reach up with my arm to clear off the blown insulation, then use a 24" ceiling fan brace kit.

How did they fasten to the 1x3 without splitting it ?
I, personally, wouldn't mount a fan to a 1x3.

You could remove the 1x3 and use one of these old work fan boxes with adjustable supports. It will hook to the joists in the ceiling (the bars extend outward applying pressure between the joists in the ceiling). This is just an example of what you could use, not necessarily this one though.

But if you do use something like this be sure it is a fan rated box, some just come with boxes not rated for fans.
