I think this is probably covered in the above, but it looks like a circa 2003, which takes a 111mm BB as mentioned. Here's the catalog picture for the 2003 Record Triple and the Tech Specs sheet for the BBs that go with the Triple. The picture isn't clearly asymmetric but I'm not sure if it's drawn to scale. I actually have a 111mm Token ISO BB on the way for my Racing T (mid-90s though). Whenever I get that installed (probably be a while) I'll try and remember to add another reply.
