I found a trumpet in my grandparent's attic when I was helping them declutter recently. I am trying to look all over the web for what kind of trumpet this is and year it was made but there is little to be found. The only markings on it are Barclays on the bell, the serial # 66547 and made in czechoslovakia on the brass around where the mouthpiece goes (please see below picture links).

Just wanted to gather more information about it for them!
