If anyone is thinking of buying an original Irvin on ebay this one is not quite what the seller claims-an early War version. He has been told its post war, with its Clix zips and the post War Lightning main zip and that these utility jackets (produced in the late 40s and 50s) normally fetch a max of £100 on Ebay.
