Mouthpiece Identification

[Richard III]

I've been trying to identify the mouthpiece used by flugabone master Erling Wicklund in this video. Anybody recognize it? Thanks.

I am really just looking for who the maker is for this mouthpiece. Thanks.

looks like it could be a Marcinkiewicz?

I kept thinking it wasn't because I kept seeing a black line around the outside of the rim. It looks like an added feature I've never seen. But maybe it is just the light and there's nothing there. Thanks.

Update on this. I didn't want to pay for the Marcinkiewicz. But in looking at mouthpieces, I noticed that the King 12C had a similar shape to the Marcinkiewicz 12C. And it was much cheaper. I got one and it has been working out nicely. In case others are looking for a mouthpiece to match with this style of horn and playing.
