you could try looking back to around 1990 squills&bhw year books as he advertised in there, might give you a lead as to where to try next, i will ask my old dad tonight as he had been down at the Stalker lofts around then and was friendly with the family, i was just a nipper then(lol) a few bad young bird seasons around then plus a change of loft location kinda put paid to the gurnays we had, looking back they never really got a good crack at it.
