Yes, these were made for export, and a five claw dragon was for the emperor, the four claw was for officials and so on, late Qing not so much although the fear of using the imperial 5 claw dragon still was in the minds of potters and so it was limited, I have one vase with a four claw dragon but on one of the dragons foot is 4 claws and one partly toe seen, it was like they wanted to draw a 5 claw but out fear a partial toe is seen indicating 5 claws or may be I am just drawing to much into it, It has been a while since I discussed this with Peter, I still have the vase that has the partial toe, but in Traditional Chinese porcelain the potters were forbidden to make 5 claw dragons they were reserved for imperial use and Four and Three toe dragons were given as gifts and used for export.
