Here are the pictures of the two F-Mezzo mouthpieces that I have. The sop and alto ones are for comparison. From left to right we have: Conn soprano, Theo Wanne Mezzo, Mezzo from eBay, Otto Link alto, Meyer alto.
Playing, with the Theo Wanne piece the instrument is very much in tune except for the D3 and higher notes. But it looks like the key heights for the palm keys are set too high. The Alto mouthpieces are way too big. The soprano mouthpiece fits, albeit snuggly. But the intonation of the horn is then totally off.
