For doubters on our last post on this subject please see the attached, which is a page from the October 2013 issue of the Allard Owners Club Newsletter with a photo of a pair of 21 stud heads made by Allard Motor Works of London England who also produced some 1500 Allard sports and other cars from 1937 to 1958
I didn't see the last post & I'm definately not a doubter - but Its always good to see vintage Allard stuff especially speed equipment
