Presenting here an early Veritas stove for information and comment. The most distinctive feature I think is the tank top spirit ring; I have never seen a British made stove set up this way. It appears to be mimicking one of the options which appeared on some Primus and Optimus stoves around the time of WW1: Could these have first been produced in the 1917-18 period when the German U-boat blockade was most effective at cutting off imports? or immediately post-WW1? The second most distinctive feature is less visible. That is the weight. Everything about this Veritas is heavy weight; from the pressure release key to the tank bottom seam to the pump tube end cap to the gauge of the tank material: On the scales, devoid of fuel, this 2 pint stove weighs in at 1095gms, an equivalent Priimus weighs only 825gms. The tank top legends proclaim 'VERITAS PUMP STOVE No5 LONDON, GLASGOW, MANCHESTER': It has taken some time to acquire an appropriate burner unit; the filler cap, however, is currently a suitably 'chunky' Valor cap temporarily substituted in the absence of an original.
