Just to say at the time of his death there wouldn't be a 'Yorkshire Fire Service'. County Brigades didn't start until 1948 after the National Fire Service. Then it would was the West Riding County Fire Service. Leeds , Bradford, Huddersfield had their own brigades until April 1974 when it became West Yorkshire Fires Service Before that they were local towns and city brigades if there was one at all. I would think that Leeds Library would be the best port of call. The Leeds and Yorkshire Fire Brigade may have been an insurance company or similar
