Any funeral home that performs cremations. They will also have the brass plates in many different sizes.
I needed a part for my new hermes. Gave them the serial number- they said they didnt make it. I sent em a picture of the serial number plate with their name on it and a picture of the machine and a link on their site to my machine. They still denied ever making it. Then the dude just said look man we're concentrating on automated machines now that machine is too old.
