Which country is this patent from?

Is the figure that the landlord saw wrong? If the landlord is really talking about patent documents, GB generally refers to British patents, and the latter one-A-is very strange. The correct reference numbers of the available British patent documents are GB2, 140, 160A, where the reference number A represents the published document. When the patent document is authorized to be published, A will become B, GB2, 140, 160A relates to a device for sensing fluid motion. I wonder if it is consistent with the contents of the patent documents that the landlord saw? A description of the patent is attached.
