Sounds like your fellow shooters aren't a lot different from many over here, they need constant reminders of what the "dangerous end" of a gun is.
However, there are no compulsory competence rules here, our Constitutional law allows any idiot with money to own a gun, as long as they have not been convicted of a felony.
As for the wooden case, the Model 27 came from the factory for a period of time shipped in one like mine, and the case size varied with the barrel length of the revolver. Some models were shipped in a package with the traditional cardboard box and also had a presentation case with them, but M27's shipped in the presentation case. Originals can be found, but as with anything collectible, it will have a price dependent on the condition. The inside of the case has a vacuformed insert with a blue "flocking", something like a blown in fuzz that is glued in place. The insert is thin and will tear or split with age and use, and the flocking wears off. You can see that mine is not pristine. The case is usually not used as a storage container, the flocking comes off and gets into the gunworks, it can hold moisture and damage the gun if left untended for a long time. I only have the presentation case for two of my revolvers, and I do store the guns in them (limited space in my safe), but I frequently take them out to wipe them down or admire them, and when replaced in the case they are wrapped in a silicone impregnated cloth to protect them.
I've only been to Belgium once, and I don't really know exactly where I was, except it wasn't far across the border with Germany. I was stationed at the time (1991) at Ramstein AB, and had gone to a firing range with a combat arms training class for a Mk19 familiarization course. Going to the class was an oddity in itself, as I was a non-combatant aircrew member (Flight Nurse), but had the opportunity to train on several weapon systems while I was there.
