It's so small that it doesn't seem like it'd be very useful other than maybe to keep a few of your most commonly used items in, and the rest in a main box; even I have way more measuring tools than I could fit in that.
-The idea is to keep the instruments in the wooden chest that are the most affected by corrosion, namely the watch movements of the indicators. Other instruments like calipers, mics, and such that use an outside reference surface can be lightly oiled, the delicate movement of an indicator cannot. Grinding vises, angle plates, and spin fixtures fall into the same "outer reference surface" category.
The small drawers are usually for gauge pins/blocks, setting rings, toolmaker chairs/buttons, etc. where corrosions will greatly affect the accuracy. The type of wood is important as well, oak in contact with steel will promote corrosion. That's one reason (besides stability) why cherry was the preferred wood for instrument cases, Oak chests have the felt lining to prevent this contact corrosion on steel, that's what I've read anyway,
It's really a personal choice what to use, Whenever I had the extra $500 to spend for work items I always chose to spend it on measuring instruments instead of a Gerstner. I changed shops every 1-3 years, too often to expect a wooden chest to stay tight and scuff free.
