CAF1 definitely looks like a roomier jacket with not nearly as flattering silhouette but as I never handled one in person, I didn't want to say nothing. But the two jackets look very different in the photos, even though they share every other detail. From what you've said, Anniversary sounds exactly like the CM1 (Confederate) jacket, which is very similar to the old Beck brand in fit. I'm fairly certain Schott was using their old Beck patterns for CM1/JRAC1 jackets. I've had a Beck for a short while and it's virtually identical to the CM1 except for the sleeve zippers. Anyway, the CM1 that I got is a size large, which Schott size-charts translate to 42-44 and the jacket is comparable to 641 in a size 38. Only marginally bigger than my Vanson Model B size 38. Really slim fitting jacket - or rather, one very rare instance of Schott correctly sizing their jackets as it's exactly what I believe an L should fit like. It's a great jacket in any case. The best fitting I've seen from Schott, without any doubt. Or I would go as far as to say that it's maybe the best fitting jacket I've seen from any brand. I just pray they never make one in Horween CXL. . .
