I purchased an Eastman RAF Irvin Early version about 10 years ago. Its been in the closet for about 4 years now as I seem to have outgrown it!! I wanted to sell it to a good home but I can't find an identifier on the jacket. It was marked as a size 38. I ordered it, at that time with a form for all the measurements. How can I identify it as Eastman when I put it up for sale??
