I’ve not seen one of these before, a Sampson Stove – I have had a look on the internet and can find nothing about it or the company that made it? The stove was in a thatched property in Great Chesterford. I swept the flue via an inspection hatch in the elbow joint of the stove pipe at the rear of the appliance. The stove itself has a fixed baffle which cannot be removed to access the flue mouth. I spoke with the customer, who told me that he had bought it from a pub in Great Chesterford when it closed down many years ago! He went on to say that it had been installed in his home ever since and had worked brilliantly without any issues.
