Wranglers were a couple of bob cheaper and I have no idea about Lee Riders.
BS also around the price of Levi's while Jaytex, like Wranglers, were a few shillings cheaper.
Brutus were not on my want list in '69.
A Levi denim jacket was just shy of a £fiver at £4-19-6d.
Thanks for making an old man feel even older, BTW!
