I tend to agree Bob

As the only one without kingposts fwd of the superstructure and the only one which hadn't been lengthened, DUNKERY BEACON is the only possibility among the ones mentioned. In the late 1960s her name would have been MARANON, under the Peruvian flag and operated by Corporacion Peruana de Vapores. That does look like it could be a Peruvian flag at the stern.

Crowborough Beacon looks likely

Hereford Beacon & Ivinghoe Beacon are similar but have kingposts in front of bridge all built by De Noord

Yes your right but I am convinced its built by De Noord simular is Hereford Beacon etc.

Does not look like Tohoro masts are wrong

French,Duch built,sisters TOHORO,TOMOE & TOROA Transportes Oceaniques

Looks Dutch built to me?

This is not the typical EAC design/profile of that time. The funnels were higher/not so compact, and had no black band on the top. The EAC-sterns were also different from this one. Niels

I looks like Danish flag, maybee the company EAC
