The entire history of the Merwin, Hulbert & Co. is very vague. Due to the bankruptcy their entire records were lost. Their subsidiary company, Hopkins & Allen, also burnt down in the 1900, taking along with it much of the records with Merwin, Hulbert & Co. As well as the manufacturing of the Merwin Hulbert revolver in Spain, records and documents are also scarce. Finding a photograph of the Spanish Merwin Hulbert revolver used by their military was also a tedious task(which is why the photo above is not a great shot of one). Many do not even know that this particular revolver even existed in Spain.
