Bish and Eric, thanks for the kind words on my 109. In spite of the time constraints, I really enjoyed this project. And with this build, as Bish said, the Airfix bug has bitten me...
Eric, I certainly agree with your point about the tools, war, and art. I have no firsthand knowledge of the German army practice of painting tools or not in WWII. But seeing how they were a leading proponent of camouflage uniforms and equipment before most everyone else, the idea does make sense. I suspect that the Wehrmacht Heer likely had their tools painted in the same color as much of their other metal equipment was such as helmets, mess tins, and gas mask canisters were painted by the subcontractors during production. Or at the very least, a typical industrial tool color like black. I do know that US Army practice was pretty much to have everything painted in OD at that time. Paint in addition to its camouflage properties also helps the tools last longer by sealing and protecting the metal and wood underneath. Of course once you start using the tools for their intended purposes the paint is worn away. But we all know how militaries love their "Spit and polish" appearances, and during downtime soldiers are given taskings of repainting everything that is not growing... just some of my thoughts on that point...
