We had the ‘propelling pencil’ chinagraph from about 1968 onwards with no change that I remember until leaving in 1975; I still have some sitting in my desk drawer both white and yellow plastic. We never had issues requiring holes to be drilled or lines attached, just stuck them into the appropriate pen pocket in the baggy green skin as required.
We only had the goose neck torch which we hung on the D ring on the front of our LSJ or flying ovies so that it shone forward if ever needed in anger. There was much consternation when a new mark of flying suit was issued without the D ring, as its purpose was to secure the O2 hose of a mask and deemed unnecessary for us angry palm tree crew for whom the new suits were issued. We must have been taken seriously because the suits were subsequently fitted with the D rings!
