Another rare find. I have been very lucky lately!
Here is a Diamond State Telephone Co. pin. This is one of the hardest pins to find from the old Bell System (especially marked 14K). D.S.T.Co. was a subsidiary of Bell Telephone Co. of Pennsylvania and was located in the state of Delaware. I missed a chance for a Lehigh Telephone pin earlier this year and it is even more rare. Maybe next time!
