Somebody on Flickr has a scan of a Bicycling Magazine review of the '82 Allez and Sequoia that includes specs. I'll attach the specs for your convenience, but here's a link to the album that includes the full scan: https://www.flickr.com/photos/leapin...57625500696996

FWIW, my Sequoia is the same size as yours. My notes say the wheelbase is 1025 mm, which is in reasonable agreement with the 40.5 inches claimed in the BM specs. A previous owner attached mid-fork braze-ons to mine so there's a slight chance that my fork is not in its original form, but I don't think that was done. If you want we can take both Sequoias over to the Atelier sometime and gugie can put both forks in his rake measuring thingy to get a really accurate comparison and possibly even bend yours to match mine if necessary.
