Okay great minds of the interwebs! I have a 1850s farmhouse that my uncle owned for 50 plus years. He was a master plumber and owned a hardware store and all the fixtures in the home were high quality but not always identifiable. It's also marginally possible that one of his sons replaced this after he passed but we have a leaking controller in the shower and the plumber is stumped about how to replace the cartridge. Neither one of us recognize the brand. Does anyone have any guidance? We are hoping not to have to open up the wall and replace everything. We just need a replacement cartridge! Thank you for any insight. This could have been from a regional plumbing company from the 1980s.
