When Allen purchased the vehicle a full set of new manufacture seat cushions came with it. We have been having some communication on this issue as I have never seen this pattern before although he has now found the original submitted as the pattern for their manufacture? It is the standard 'D' shape, common on both Canadian and British seats. It has an opening at the rear with eyelets both sides, obviously for lacing up once the insert is in place. It also has the 5 eyelets on both faces and two sets of hold down straps so it could obviously be reversed, anyone throw any light on this particular pattern?
