Not to be outdone (who says size is not important?) this was my first scope, 1961, an 11th birthday present from my Dad. http://www.thevalvepage.com/testeq/cossor/1049/1049.htm Busted and scrapped by

Luxury! My first scope, aged 16 was a Hartley 13A, and real just-post-wwII behemoth. For pics of what this pretty useless performance beast looked like
