Obviously a builder with the initial "D", but who might that be: D'Allessandro, DeBernardi, DaVinci?
Thanks for the info on Wavre. I found out that G. Vanconingsloo is the name of a former racer who now owns a shop in Wavre. It's definitely a competition frame as the place I bought it from mostly sells used pro team bikes.
The thing that I think might help to nail down the tubing is the top tube which is flat on the top and bottom. I've never seen or heard of tubing like that before, surely it must be rather unique.
