Pennco Gas Boiler Age

At today’s inspection a Pennco gas boiler was at the property. I called the manufacturer for help with the age of the boiler. The rep said using their current decoder for serial numbers, this unit was manufactured in 1951. The 9 was a model code and the 51 was the year of production.

Wow, was it operational? Do you have a pic of the whole unit?

I have a picture but it’s not very clear. It was operational. Some rust on the unit and a slow drip from the TRV.
