Try to find the papers. There should be a vaccination card with them, and a pedigree. The vaccination card varies hugely with the vet, the pedigree is probably printed on a sheet of A4 paper or card. There might even be a kitten card leaflet the breeder printed, and a receipt. You need the vaccination card - if you ever need to board your cats any reputable cattery will expect to see it. You can also check if the sex on the papers matches your kitten!
If he is 16 weeks old then it will be a white post-card size card with GCCF in moderately large type - it changed earlier in the year from a pink slip. It would be polite to let the breeder know the kitten is safe and well.
Kitten looks quite happy in the photos, sounds like introductions are going fine, at some point you need to let Oksana in when you are there. Some kittens are very confident and fit in very quickly.
