".....the fact that blue globes marked "EMBURY NO. 40" are known to exist --- but the catalog clip on the Embury page shows no blue globes in the Embury line. Perhaps blue and amber globes marked for Embury were ordered by Dietz in Syracuse for the Embury factory in Warsaw after 1953." Excerpt from this website. A conclusion could be made that a Blue Embury #40 is correct in either an Embury or a Dietz TG.
