barebow17,
Someone gave you an accurate description on how to identify the year on a post I saw somewhere else. If it is double shelf 1955-56 Silkscreens 56' decal 55'. The 57' and 58' will be single shelf and the 58' will have white glass. I will try to take pictures of the 55, 56 and 58 I have. I don't have a 57, darn it.
