Rohaaan,

I have quite a bit of Elswick information, including reproductions of some adverts and catalogs, and an article about the factory from 1949. I would bet that I have some information about your model - I'll look through my files this evening to see for sure and post what I've got. Meanwhile, I added some information about Elswick to my blog in case you're interested...the first of several installments begins at http://marksbikes.wordpress.com/2012...-bike-project/

Cool bike and cool head badge!
