Hi everyone, I am new to the site and would like to introduce myself. I live on the south coast of England where I play in two bands, one military marching band and a swiss style 'GUGGE' band. i play an Olds ambassador trumpet of 1960 vintage and an ambassador cornet dating back to 1964. I have just bought a rotary valve trumpet from an auction held in a village in the new forest. It has a registration document in what i think is russian. It has a logo a bit like a capital A but without the cross piece. can anyone help with identifying this horn? Rob.
