Was Tony Baker, an Australian Navy chap on exchange, or maybe doing the Sea King conversion, as Australia was to take delivery of it's first aircraft in 75 - 76 I think it was. Did get a gong but can't recall which. Salt accretion on compressor was the cause. Won't be home for a month or so so unable to pass on his email address. If you can hang out till then ralphmalph can put you in contact. Tony went on to do the Pax River test pilot thing.
