As usual in the case of Spanish patent data from Espacenet, we all are treating "priority date" information not as the invention's actual internationally significant priority date but as the filing date of the Spanish patent itself. We have found that the patent titles seemingly unvariably match the title and contents of patents filed elsewhere, with the "priority date" associated with the Spanish patent never being the earliest date. This patent is almost certainly the Spanish equivalent of Patent GB-1909-2111.
