U-154 No embossing. There is no damage to speak of. This style has been known to be super crude in its dry process manufacturing. It seems like they were just trying to rush them out the door with no quality control which is cool because each one is unique.
U-177 No embossing. There are some chips on the inner petticoat but that’s it. Very cool bell shaped insulator.
U- 179 No embossing. There is one little nick on the inner petticoat but that’s it. This style is signatory to the PRR (Pennsylvania Railroad) which I’m fortunate to live near. They made these in glass but the porcelain ones are harder to come by.
I always combine shipping to help you save. If you have any questions feel free to ask.
Thank you for your interest and Good Luck!!
