Ed Gilkison Velocette

I was talking with Bob Strode a while back ( who had this Velo parts & service business for ten years before me, and I have had it now for almost 30 years), and told him I remember seeing him and his brother Jim, on the cover of 'Hot Rod' or similar magazine years ago. He said he had a couple photos from the photo shoot - and sent me these copies - but never seen 'em appear in print. Was hoping someone in the group into cars, might be able to help with the search of which magazine it appeared on - I believe was in the mid sixties - Thanks! Ed
