Here are some photos of one of my Mk I*** bolt heads, as promised.
Unfortunately I believe the gentleman who ran EFD passed away a couple of years ago. It would make restorations so much easier if resources like him were still around.
Thank you for the pics. It looks like bolt head has been spared by bubba. I did get an email back from the folks at EFD, might be able to get some stuff from them. I wish I was collecting Enfields ten years ago. Always clearer in hindsight.
