I know little about the sorts of crown lugs that were available for old forks, but I was a little surprised to see the one posted by the OP. Was the card suit motif a popular item for forks, or was there a particular manufacturer who made these things? I ask because a couple months ago, I posted a fork that I had purchased that had similar cutouts. We determined it was a Charles Roberts, and it is a very nice fork. It has the some of the same design elements as the one the OP pictured. Interesting.
