I was referring to the cloth mask and the 'cage' which holds the microphone. The style of the lettering and number (6D/117) is exactly the same as the Sefton reproduction items. The style of the '1' appears to be different in form from the originals I have seen. Have a look at the picture of the Sefton example I have attached. The problem with these oxygen masks is that they go for mega-money, and the ones offered by Sefton are uncannily accurate in detail. Only slight differences exist between the repro and the original.
