T2 Trainspotting star Bradley Welsh recovered a shotgun which may date back to the 19th century, a trial heard. The court heard how the Belgian-made weapon was recovered by cops last year from a garden shed in Lanarkshire.Giving evidence on Thursday, ballistics expert Martin Connolly said the shotgun could’ve been made as long ago as 1890.He added the old-fashioned gun was fired by pulling back the hammer with the thumb before pulling the trigger.
