I thought they were all red labels, but pulled some at random, mostly blue.
They all say either recorded in Europe or recorded in England - but all read 'made in USA'. Based on the links I posted, from '53 - '57 Angels were imported from Europe, then after that made in USA.
I'll have to go through the boxes in the garage for some of the copper colored labels the 2nd link I posted speak of, I think I may have some.
