Thank you! But I have one in poor condition, much like the one you replaced.
Joe Suchy is looking for a good one so he can use it as a template to have it reproduced. He doesn't have anything at the moment.
I think this must be Rubber Seals Australia - see post #568 in this thread. They have something that will work, but it's not a repop - those won't be available until the end of next year.
