I doubt the date is fake. My date is 220103
The bottles have AB I'm pretty sure this is old stuff. Made prior to Covid and the apparent collapse of Sino Promise. I wonder if Wuxi China plant is still going? I will use this, no worries.
I think those are best before dates, not manufacturing dates - No AB on the code. The sale of that business segment to Sino Promise completed November 1, 2020.
AB is date of manufacturing.

I've recently started seeing new black and white products on local store shelves. Kodak branded, but Sino-Promise small print labelling. Some manufactured in China, some in Germany.
You earlier indicated that your bottle had a code of 03012022AB.
Is the code actually 220103, or is it 220103AB?
I'm just gathering information to aid in understanding the situation - not wanting to challenge.

From our date codes it appears to be Sino Promise made color chemistry.
You should be safe in doubling both the number of rolls before incrementing the time and the total number before discarding the tank solution.
Of course, with LORR replenishment, you can process about twice as many rolls before you use up a liter of replenisher. After one liter of replenisher, therefore, you're about even with reusing the solution and extending time; continue replenishing, however, and you start to save significantly -- your one liter of startup (which actually needs only about 3/4 liter of replenisher plus some starter and water) plus two liters of replenisher can do more than sixty rolls (vs. ~48 done as above -- accounting for each liter of working solution using only about 3/4 liter of replenisher to mix), and by the time you've used up the 4+ liters of replenisher left from the original 5L package after mixing a liter of tank solution, you'll have processed close to 130 rolls (vs. ~75 rolls with reused and extended development as above).
Of course, Kodak recommends keeping the replenisher for a maximum of six months, but in good storage (wine bags, Stop Loss bags, etc.) it'll last longer than that. A year is conservative if your storage is impermeable to oxygen. And PET bottles upcycled from soft drinks work great for storing the tank solution.
This is a 3-part concentrate, right? One of them is a smaller bottle than the other two. What color is the liquid inside?How long would unopened concentrate last?
The unopened stuff is OK. Not sure about the working solution.
You don't think C is too yellow?
You don't think C is too yellow?
Your C looks just fine, really. If this part goes bad, it looks virtually black - or actually a really, really deep shade of purple if you hold it against a strong light. Yours is straw colored which is perfect.
I expect your kit will work like new.
Start should be very stable even under suboptimal conditions. Yours is likely fine.
