I finally had the chance to go out and look. After scraping at the rust on the ends of the pedals I was rewarded with one R and one L. So this is good news. Interesting that everyone here was so confident there would be one left and one right. Got to see if I can find where I read that about them having two lefts....

Oh yeah, on the Blayleys site, http://www.blayleys.com/articles/tandem/index.htm

Well I'm glad they were wrong and you all were right. Thanks.
