Denis Wick 4882 Trumpet 3E

I am not faulting the quality or putting any fault on this mouthpiece. It just does not suit my cakey bun hole at all.

Update, thought I would give it a couple more goes before putting it on Ebay. So, after a short while of extreme buttock clenching and squeezing my head in the doorway, I managed to get a note out of it, then a few more notes with less effort and before long I was blasting out 3 octave G minor pentatonics with ease. This is not just good on the high notes, middle C and low A have a beautifully mellow darkish tone which I think is incredible for this type of mouthpiece. It actually feels really nice on my lips too so this is now my main mouthpiece.
