Just picked up an estate GBD 9438. Under the GBD stamp is the Congress stamp. I cannot find any info about Congress being a grade, and what I can find in relation is that the folks who have one, don't have any info about it.
Can any of the GBD collectors enlighten me as to whether Congress was a grade of pipe?
