I think I solved the mystery. It appears to be an Emile Warnant. The makers mark punch is a bit strange, but it appears to have an EW under a star. It has bushed strikers and appears to have gas valves in the fences. The selective ejectors are strong. It makes me sad that this gun was not maintained as it should have been. It is very nice. 6.6 lbs with 27.5" barrels. Sadly, my pictures fail to show how lovely the wood and the shadows and depth of the engraving. The rib is marked either with the owner or retailers name of "W.A.M. Valkenburg A. Tilburg". Please share your thoughts or redirect me if you feel my conclusions on the gun are incorrect. I love to learn.
