Hi Kyle,
Yes that is a 26 on the funnel - and many thanks for the information - I was hooping for this level of knowledge by posting here.
Many regards,
Douglas.

I see the #26 on the funnel, presumably for the 26th Escort Squadron. The only vessel of the right configuration assigned to that squadron was HMS WHITBY F36, assigned from November 1964 to January 1966.
