Have one of these, very good clone of a Diana 34 with the T05 trigger group. You can use the seals and springs for the D34, and some other parts too. If you take the trigger apart, just take notes of the position of the two sliding plates, the rounded edges goes toward the rear. Congrats on the buy, they're usually very accurate and reliable rifles. Have fun!
When you say round edges, do you mean the found edge of the center hole?
I can't get it to latch regardless of the sear plate orientation.

Well this thread has inspired me to get my $75 Tractor Supply bargain bin BlackHawk out of the closet. There’s a thread here somewhere about my trials and tribulations with it the first go round.I disassembled it, de-burred, cleaned, and polished everything I could reach. Put a new Maccari piston seal in it. Discovered that the shaft running the length of the piston was loose. Put it back together and shot it. Still grouping about 2 1/2” at twenty yards.Next step is to tear it apart again and try brazing the shaft in place with a torch and solder.

He may have the part and you won't have to try soldering it.
Not sure what is causing the 2 1/2" spread but I doubt it is the loose latching rod.

The shaft has quite a bit of play but I’m pretty good at sweating pipe so I think this will work.

No guaranty that it’s an accurate pellet in this gun since it has never shot well enough to determine which pellet is best for the gun.If fixing the piston is not sufficient I’ll take a look at the muzzle crown.
The loose body on the piston is not the problem (shaft is press fit into head of piston, if loose would pull out), recrown is in order and use good quality lead pellets. 4.52 head size seems to work best in most....a light deburr of the breech may help also
