There's a lot of detail about Sea Vixen squadrons in Tony Buttler's book*. It shows Lt JW Harvey on 890 Sqn from 17/12/1961 to 20/10/1963. He subsequently appears to have joined 893 Sqn when it reformed on 4 November 1965. XS581 arrived on 893 Sqn on the 10 November 1965, but is stated as having a nose number (or side number in naval parlance) of "241", and not 382. Hope this helps.
