Another example of this sad failure of British stove innovation. Infamous for attempting to be too clever-by-half in the innovation stakes, whilst at the same time failing dismally when it came to basic production quality control. These issues are already well covered in detail in two previous posts, here and here. So it will come as no surprise to be told that this example is plagued by the usual tank stress cracks. On the other hand, however, there is some merit to posting this further example. First, it provides an answer to a question raised back in 2011 as to what burner was originally fitted. The answer is that Shaws had their own burner made specifically for this stove, and this is the first example to have come to light: So now we know. Secondly the clever lockable pump mechanism is almost like new, enabling very clear illustrations to be made available: The tank looks superficially decent: The stress cracks, however, are certainly there, in this case at least 6 spread around the bottom edge flange: It is, nevertheless, just sufficiently intact for a demonstration burn:
@igh371 a good find and a pity that these stoves suffer of stress cracks. It’s funny to think about all the efforts made to seal the pump NRV with that clever locking system (like primus 76/77 etc. and some lamps as well) and have multiple leaks for poor quality control on the brass forming… The synthesis of life.

Yes a real shame considering the attention to detail in all other areas- reinforced riser to tank joint, external NRV for ease of maintenance, lighting device, broad feet... it must have cost a fortune to develop and tool up to produce. The locking pump seems unnecessary extra expense, although at the time any such innovation was surely desirable as a marketing feature over the long established Swedish brands. I suppose however it would get a meal finished or allow cooking for a few days until time or parts could be found to service the NRV. But in combination with an easy access external NRV it seems even less useful... Anyway, very nice, very interesting, a sad case of 'if only'.
