...sometimes, on the larger size frames, the builder might sub in an SL seat tube, instead of an SLX. It's risky trying to fit s post to one of these just by referencing the marque and model. And different frames got reamed to different final sizes in a lot of hand built operations.
If a 27.2 post fits in there now, but seems a little snug to you, there's a good chance that it's the correct post. If the snugness bothers you, try cleaning up the interior of the seat tube with some abrasive paper wrapped around a dowel, and the exterior of the post with a fine abrasive paper as well. The grease or anti-seize applied lightly to both surfaces, reinsert, and clean up the mess at the seat post insertion point.
