Sapientia et Doctrina Stabilitas
Quick update: I finally called Mr. Steel and they said they never stocked cast iron, it’s just listed on their website. Instead they recommended McMaster. I ended up calling terranova and they said they can do small orders but I need to give them the exact finished dimensions
This sounds familiar... so I guess I must have resorted to the barbaric practice of making a phone call during business hours and got mine from terra nova. Thanks for letting us know where you ultimately got yours
