Documentary images — company attribution uncertain

A812 is recorded under H. F. Aldecoa. Rosanoski assumes the same company from the name and Bilbao location, though the wording suggests an individual and Mitchell names no vessel.

Individual/company relationship and actual vessel use remain unknown.

The source combines Aldecoa y Compañía, H. F. Aldecoa and possible Manila associations. Bilbao evidence supports Spain for that owner, but does not establish that all three flags represent one entity. The suggested 1937 start cannot describe all Aldecoa activity.
