I would like to buy one of these neat blasters from Miraphone. I believe they were built in three separate configurations. Two of them had a 4 valve configuration and one of them could be played in F/Eb and there was the standard 3 valve model in Eb. To be honest, I don't mind which model but I would like to get my hands on one for a decent price.
I've got an older German one but I would like to upgrade. I intend to play the Hindemith on it in a concert later this year and I've already performed a Suite for Eb Bass Trumpet two years ago on my crude German one.
Trust me, it will go to a good home.
