I think I know what you are asking. The kitten will look like a female to most, since you are a retired breeder, you will be able to tell he is still a male by knowing the distance is further for a male than a female. There will be not obvious testicles, and because they are still young, there isn't a skin flap left over. I have never thought of taking pictures, but I will have a male going in a about a month from now to be neutered, and I can send you a PM of his picture after neutering. So I hope my answer help you, in that in most eyes, he will look to be a female.
I have to brag a bit about our vet. The males have only one dissolving suture, when they come home playing and you look at the area, you can't tell the males have had any type of surgery, except certain parts on gone.
When our vet does our females, he only does a small shave that is about 2 inches long and a very thin strip, where he places two stitches that are removed 7-10 days later. We usually take our kittens in at 11 weeks, and we just like to keep them together as they heal, but the healing is just letting us have another week with them, and for them to learn more kitty etiquette. Then they leave for home at around 12 weeks of age, as long as they all seem mature enough, some have stayed longer.
To help in any fears you may have, in the few years I have practiced early altering, I have never had any issues after surgery, and no issues have surfaced in our males or females that would indicate any problems associated with pediatric spay and neuter.
