In other words: It's part of my daily work to look at random peoples' old stuff, make a source species ID and tell the owners if they need to apply for a CITES-permit/certificate before selling the item in question. I also work borders with our customs agency, ID'ing items coming in through the mail as well as carried by travellers in the airport.
My thoughts on topic of hippo ivory in the context at hand, are much in alignment with Allan Maisley's. Like Allan, I would also very much like to see written proof that hippo ivory was carved and used in this way in South East Asia. Please note, that I don't say that I do not believe it, simply that I would like to see the source. In the face of new evidence, I am always up for changing my opinion!
Secondly, and for me more importantly, I would like a source to “dots in a row” being a sure-shot character for the ID of hippo ivory.

Hello Thor,
We are very lucky to have an ivory expert among us!
Personally I am convinced by your arguments since you are the specialist and admit that I have been too quick to accept the presence of the dotted line along with other qualitative or visual indicators (feeling of higher density & hardness, colour, structure) as a proven indicator that a piece is made from hippo ivory. I agree that this evidence was not sufficiently documented.
If my question is not too difficult, could you please tell us how do you positively identify carved hippo ivory pieces subject to your inspection?
And a more detailed one: did you ever notice a dotted line in some pieces identified as spermwhale ivory?
If I have the opportunity to meet you I will be glad to show you my pieces in question provided that your Customs Authorities do not seize them
Thank you and happy New Year!
Jean
