Rik, by tracing, I used the original to determine the arcs and using the Ctrl key and other vertical and horizontal adjustments of the line nodes, I have a completely symmetrical cog. There is therefore no guesswork.

Egg's "Raw [sic] by eye" is similarly "not accurate". siran's equally has some judgement required. Gary's is fitting points in a way close to mine; two of the lines have to be best guesses. Yours has its nudge points. Only ernie-f's nails it for accuracy to the original.

siran's is the best for the tip, yours for the profile.

In the end, a hard call but an enjoyable challenge.
