Thanks for that correction, one learns something every day.
Going back to the original large format photo I found in the first place, I can now see the little "i" stuck in the arms of the "J".
I think my original search was for something like "Ford 1950 van Netherlands" on Google.nl and this photo came up.
I saved it and waited till the photo got up to the Pro level. As the photo was too large, I reduced it and you cannot see that detail on my answer photo. I will post the original here for a day or so and then remove it to save bandwidth.
This fact is also the reason why I could find no other bodies by Fa Wunveen, they did not exist
