Gary, I had to read between the lines and unrelated comments, but I'm now guessing your supposition is that the barrels, assembled, minus ribs, were made in Belgium, stamped as un-proofed, and sold to Remington. Is that right?
You didn't actually say that, and I'm not trying to put words in your mouth, just what I think you're saying.
What I originally said, I still stand with, that Parker and Remington would never stamp that location, is because, as seen in the first pictures, it's finished ground. IF (BIG IF) you're saying they were made by 'others' and sold to Remington, then it is entirely possible they were stamped there, as that surface had, as yet, to be ground.

Having said all that,(1) The WL3 code would almost certainly be when the barrels were fitted, But it's highly unlikely they were exported anywhere around that time, because of the WW2. (2) This was only 7 years after Remington acquired Parker, and we know there were plenty of already made barrels, made in Meriden, that went to Ilion, Remington had been making barrels at that time, and Remington sold Delgrego all remaining parts, which included Lots of barrels (1 1/2 frame being about the most commonly produced). Would Remington have stamped all the other information (in the relieved area) Such as unstruck weight, Parker material grade, HT over A, when they would have been heat treated and annealed in Belgium, and The Remington Version of the overload proof ?

Art Wheaton is probably the only person, because he worked for, and at Remington, who might know if any barrels were imported for relatively 'vanilla' guns because they still made their own (Though I don't think he worked there in the time frame these were added).

Soooo, I stick with what I originally said about them not stamping on bearing surfaces, meaning FINISHED GROUND surfaces.
Also, You are not right OR wrong, because it was your theory, not a known fact.
Lastly, the 'silly dancing Lion' doesn't match the image from your tables very well.
