Hi,
I think I have what you're looking for, see the bottom right one in those pictures.
It's a teacher, wider than phantoms, and with translucent inside, only the side of the meeple is coloured. Phantoms (left column in this picture) are also coloured inside.
I'd sell it for CHF 2.- plus shipping costs. If you're still interested, please send me a personal message with your home country so that I can calculate shipping costs.
Regards
