|MARION GREY, COLINDALE, NO. 7|
This is not a needle brand listed in Susan Webster's catalogue, as far as I can see, which is quite exciting. I suppose it's possible that Marion Grey was a knitter who had a set of needles with her name on (just as you can get personalised pencils and other things with your name on) - but as someone who loses knitting needles far too often, I think that I'd want to put contact information on mine. 'Marion Grey, Colindale' wouldn't be sufficient to find her easily. Another possibility, which I think is more likely, is that Marion Grey had a yarn shop in Colindale (an area of north London) and had needles made to publicise the shop. Or, just conceivably, maybe she had a knitting needle factory?
If anyone knows anything about Marion Grey of Colindale, please do let me know.
