These two are from the 30's (top) and 60's bottom. The Square D Co. logo plate came from a Square D Co. building in the midwest. Its pretty thick too. .Just something interesting to look at. Sometime in the future I'd like to find a nice Trunbull Electric Mfg. Co. box to restore with a nice logo on it. I have a small collection of porcelain electrical items from them that the box would look nice with. Hope you enjoyed the photos. Take care stay safe and be well to all.
