If you go to that thread I started (it is in the stickies on the Enfield section) you will see in earlier reports that there were a number of them converted by the end of 44 I believe, and conversion went all through 1945. You may have to look at the attachments while also looking at the text I have posted in each post to determine the dates of the attachments. In hidsight, I should have just put one attachment for each post.
