If you need to ask anyone, the obvious choice is Ecoflam, EOGB do not make anything remotely like this specialist piece of kit, but they will only refer you to Rayburn as it is a specific item for them. Abgo will be able to tell you if the Ecoflam unit is available. The one problem I can see is whether the stud that holds the blast tube mounting flange on the Ecoflam is in the right place, or can be adapted. I dread to think how much one of these would cost.
