I've not looked at the site, but I'm thinking that you may have a TH300; I think that's what it was called. I actually had one. The metric pan callout is what got my attention. That looks like the TH 300 I had. Or it was a TH350"c" or metric unit. Anyway, just something to think about.
Norm, the 2004R pans have that "METRIC" stamped into the pans. It is for sure a 2004R Ausbird has.
