SIT,

I bought a sideplated BLE quite a few years ago. The gun is very well made. If you go to Guns International there are a usually a few for sale. Geno, from Russia, provided a link to Littlegun in Belgium which has the most info I've been able to find. F. Dumoulin has been mentioned in a couple of articles in DGJ. An old company and very influential in the 19th C. Belgian trade. They have made guns across the entire spectrum from the most basic to the best.
