Looking for an old stem trap vendor.

We ran across a steam trap that is built into the convector as part of the radiator.  The cap contains the steam trap.  The name on the trap is Warren webster & company  # 7 valve.  I would imagine that they are out of business as the building appears to be over 100 years old.  They were made in Camden, NJ.  Is there anyone out there who has encountered these traps?

    That's "Webster System Radiation"

    and I believe it uses the same Tunstall or Barnes & Jones kit in its trap as is used in the Webster 02H traps. This radiation is definitely newer than your building.

    Webster closed its doors in 1969 or so after a long and glorious run in the steam heating business. Dunham-Bush (now MEPCO) bought out what was left at that time. But Webster systems continue to run, and will outlast all of us with proper maintenance.

    Be VERY careful removing those trap caps. Hold back with a bigger wrench than you have on the cap. You don't want to rip the trap off the convector element!
