Soldering iron elements (Hakko type, 24V) (Reepham NR10)

Two 24V 50W soldering iron elements that might fit Hakko 900 series irons and clones. I bought them in the hope they'd fit the Yihua K917C iron on my 995D soldering station (they don't). The two seem to be pretty much identical. The "Hakko" one claims to be made in Japan. I assume it's a Chinese fake, but it should still work.
