For the one of us still interested in this, looks like Henri Pieper and Louis Muller were the major Belgian makers of Folsom imported guns. Muller registered twelve trademarks 1889 to 1894 including: Acme Arms Co., Club, Climax, Star, Crescent and Crescent Arms Co., Rival, Standard, Meteor, and I.X.L.
Here's a W. Richard by Muller (at least he added 'Belgium')

Wilmot by Peiper

Here's a Lefaucheaux Action W. Richards, but I don't find 'DD' on PeteM's list of marks DD in an oval lying was used by Jean Delcour-Dupont de Fraipont-Nessonvaux



Stanley Arms Co. was made by Francois Dumoulin http://www.littlegun.be/arme%20belge/art...%20cie%20gb.htm
Later T. Barkers may have been made by Theate who's mark was 'TF' in a rectangle
