Unless that TT is obviously damaged, I'd wager it was done intentionally back in the early '80s when "aero" was the latest rage (for about a month and a half or so as I recall...). I recently had a matte-black-anodized Alan with 50th Anniversary parts, and the TT was ovalized quite a bit by Alan - definitely done "at the factory."
