This was sent to me by a reader of this forum in Belgium. I am afraid that I would be lost trying to stumble over the French however.

Sir, first my excuses that I not reply to your topic on the forum. I am affraid that my english is not good enough for the topic. I see that Cornell Publications propose a book on Belgium gunmaking and believe me there are other books that are more valuable that what Cornell propose.
1. La publicité dans l' armurerie Liégeoise et belge
2. Les armuriers de Liége en catalogues (1892-1930)
3.Le qui est qui de l'armurerie Liégeoise (1800-1950)
4. Quatre siécles d'armurerieLiégeoise or the next edition Cinq siécles........
5. Bayard-Les Hommes,les armes et les machines du chevalier-Pieper & Cie (1859-1957 bu Michel Druart
The first four are from the same author Guy Gadisseur. Even if you not understand one word of french it is valuable.
If I can give you my personal advise it is not a good investment to buy this Cornell publication.
