I ordered it at Pickguardian. The very first rippers had a nitrate tortoise pickguard (which is very prone to shrinkage/warping/desintegration). Since this is a '74, it probably had this guard when it came out of the factory, but when I got it, the pickguard was gone, and the electronics were held in place by a piece of spraypainted plexiglass, trimmed to shape with a blunt axe. Mailed Tony (Pickguardian) that I needed a singleply tortoise guard, but I couldn't give him a tracing, so he made me this one, fits like a glove. Ever since then, Tony is my pickguard wizzard
Here's a (very young) Nick Movshon with his tortguard Ripper
And the modded one I handle.
