Just picked up this little old Diana. It's a D24 .177 cal with a white factory paint job and a 'Star' moniker plus snazzy stripes added to the usual outfit. These guns, alongside the Diana Sport (brightly painted D34's), were all the rage for a short while in the later 80's, in Diana's attempt to meet 80's esthetics / buying audience. I used to see these in airgun ads back then, as a school kid, so, there's a measure of nostalgia working on me here. I already own a blue Diana Sport, and now I have a little sister for her.

If the 80's paint job wasn't enough to tell, my new gun is stamped Made in West Germany; the tiny 04 / 89 (88?) stamp at the back of the receiver brings the dating job home. This gun was apparently made mere months after my blue Sport.

The D24 lacks open sights, which is a bummer. The factory sights in these 80's guns were MUCH better than what's presently available as replacement parts, or on new guns.

The barrel and the receiver are somewhat beat up, a little rusty, the bluing has worn off in several places (a first for me), and the 35-y-o. paint job on the stock has chipped on almost all edges, in addition to many scratches. It really wasn't the brightest idea Diana ever got, in terms of longevity.

The gun cocks and locks smoothly and solidly, after all these years. I haven't had a chance to shoot it yet. I don't think anyone has been inside this gun since it left the factory.

The Diana has a T01-type safety and a trigger adjustment hole in the trigger guard, which both promised a good, adjustable trigger, like in my Sport. But the trigger blade is a stamped steel blade without any adjustment possibility. The trigger seems to have a long first stage and something resembling a second stage wall just before the trigger goes all the way back.

With the not-so-hot external condition, I paid just a small sum for this gun, not enough to buy a Chinese entry level rifle new. This is still a German gun under the paint job, something that can shoot with terrific accuracy for a really long time.

At this stage (and in the pics) I have scrubbed the gun's metal parts with Ballistol-soaked 0000 steel wool, adjusted the overly tight pivot bolt and cleaned the barrel with both dry and Ballistol-soaked patches. I want to see how the old girl shoots as is before taking the (likely very) tired powerplant out.

very nice old gun find , and the paint looks in great shape !
 
Took the first couple dozen shots with the small Diana. In short, it simply works. That is something to behold, given the 35 years she has under her belt, and many years without use.

The cocking stroke is surpringly short, ending abruptly "midway", compared to my usual springers. But the gun cocks with satisfying solidity. The safety works like charm, every shot, and the trigger is better than I anticipated: it has a medium-length first stage that reliably stops at a second stage wall. The trigger pull is a little harder than my preference, but workable, and the break is easily clean enough.

I don't have many lightweight .177 cal pellets to choose from, the obvious preference for a small-engine gun like this. But I tested and chronoed Exact 4.52's, Exact RS 7.33's, and Finale Match 7.56's.

The JSB's chambered almost too easily, dropping into the leade without resistance. The Exacts averaged 168.9 m/s / 554 fps, for 7.8 J / 5.7 fpe, while the Exact RS's averaged 172.9 m/s / 567 fps, for 7.1 J / 5.2 fpe. Cycle-wise, the Exacts are too heavy for the little lady, increasing recoil and noise compared to the RS's.

The Finale Match 7.56's were the best match for the Diana, averaging 177.9 m/s / 584 fps, for 7.8 J / 5.7 fpe. The Finale Matches chambered with proper resistance, and shot without any recoil and very little mech noise or muzzle report, outside some twang.

So, the gun shoots just a little hot for the Freimark (German legal limit). I think the D24 could be a 10 J / 7.4 fpe gun without compromising the sweet shot cycle.

There's a whiff of dieseling present, no surprise. A thorough teardown, clean-up and refreshing is in order here, but I'll just shoot the gun for now, it is so much fun. The only problem is the gun has no sights, and I don't have a scope with me, so it's sighting down the barrel for the near future!
 
Turned out the D24's single-sear trigger was just too heavy for accuracy: I had to either pull or squeeze the trigger so hard on the lightweight gun that any and all artillery technique went out the window, with resulting degradation of accuracy. It seemed the three-ball 'deluxe' trigger some of the D24's had would've been a dealmaker level improvement.

To see if anything could be done to improve the unadjustable trigger, I took the little Diana apart. Turned out there was an internal rust fest going on (see pics.). It seemed clear how the caked-on, sandpaper-like corrosion on the trigger pins, sear etc. would hinder the movement of these small parts.

I soaked and scrubbed all the parts in a mix of transmission oil + paint thinner that has proven especially effective on rust, then oiled / lubed parts where necessary and also stoned the machined trigger sear for a smoother finish. The result? The Sweet Painted Lady's trigger pull is now perfectly light and smooth, yet with a solid (false) second stage wall. A massive, decisive improvement!
