today, I found a thread with some pictures of ka-28, I'm beginning to think that there are more ka-28 in China than we all originally speculated.
These are the numbers mentionned on sinodefence
East Sea Fleet: 9114, 9124, 9134, 9144, 9154, 9164, 9174, 9184
South Sea Fleet: 9664, 9666, 9454
if you visit this thread, you would notice many more ka-28s
for example, we can clearly identify from the pictures
9664, 9334, 9474, 9224
and possibly
9264
So, we've identified at least 4 new ka-28s with these pictures and probably more
