The Martindale Smog Mask (Figure 7) was a metal frame holding a replaceable gauze mask. It was designed to filter the particles out of the thick fogs or smogs so prevalent in Britain up to the mid 20th century. It is now marketed as the Martindale Particle Dust Mask.
From about 1920 medical dictionaries did not recommend the general use of oral respirators for everyday use, especially in children, as the moist atmosphere generated within the apparatus harboured and encouraged the growth of bacteria. It was thought better to apply a handkerchief or, better still, to breathe through the nose where air was naturally warmed and filtered.
sorry to disappoint you but I have found the drawing and "BRIT. PAT. 1075346 & OTHERS" was only added to the mask in 1974 hence the mask is newer than May 1974
I suspect that somebody has been using the goggles to do some DIY or something
