Another L&B electroplater is Lingard & Baker of Birmingham but none of the L&B marks illustrated by silvercollection.it match the marks on your coffee pot. From a style point of view I would say that the pot could have been made at any time in the last 150 years. It gives the feeling of that somewhat lazy description “hotel ware”.
Thanks Phil… yes, I’d considered Lingard & Baker as well, but not similar enough. I guess ‘Hotel ware’ means a step up from utilitarian, but not high end? Although, I’d love to stay at a hotel using this type of silverware!
