Peter(PeteM), I think your suspicions on the Sl tube makers mark being of Belgian origin is one step closer to becoming acknowledged or vetted. I really don't think it is Brothers Jamar but their source for tubes. The stamps looks very similar and I think the probability of a tube making firm in Liege & Suhl to have the same stamp to be very low. So one of the Liege firms with a Krupp license, and other German I'm sure, was being sourced by the Suhl craftsmen.
