"Orange line" composition

[whiterabbit]

I noticed in the "countrymans diary 1939" that in addition to standard safety fuse and commercial blue sump they describe a very fast fuse called "orange line" a burn rate of 90ft/sec is given along with the statement that its somewhat noisy. The description implies that its the same diameter as standard but with a larger diameter burning core which doesnt appear to equate to taped black match. I think it must contain some form of flash powder but am interested to know if anyone knows any more about the composition/ manufacturer/ commercial? etc

Thanks

Is there a (free) pdf version of this book available somewhere ?

Fuze, instantaneous had a core of one or two strands of quickmatch.

Hi Whiterabbit, a little more info here: https://www.bocn.co.uk/threads/rather-ignorant-question.72414/#post-150312 . If I remember correctly Fuze Instantaneous had a raised line along its length to help with night-time identification. Fuze Safety was black in colour and had no such raised line. XT
