The oldest model M plates and model F backplates. What treatment do they have to make them that awesome colour?
That discolorations is distinctly from some from of heat treating. My guess would be annealed to work with easier then hardened a bit to hold the shape.
I'd agree with this. It definitely looks like a heat treat process.
Approximately how many times can a set of doubleshot ABS caps be taken on and off a board before they'll start to get loose? Is it much different for other plastics? What variables, if any, affect the rate of wear?
I've had my Valentine's set since I started on Geekhack about a year ago. I've swapped it on and off different boards probably 10-20 times. I haven't had any issues with wear. I suspect it's negligible wear since you're only doing it say once a day.
If you really want, you can look up the material properties and then see what the durability, creep, and modulus of elasticity is. This will give you a general idea of how much wear and usage the material can take.

just a guess, but probably a few hundred times at least. If you run into issues, you can up plastic bags and use them.
Dorkvader is saying you can use cut up plastic bags as shims if the caps become loose.

I don't remember where but I think we had an entire thread arguing about this once.
IIRC that thread was about how long the stem lasts on the switch not the cap.
Links guys?
