Another unique V8 tool

[nospartsman]

Here's another V8 tool that was in my parts of unknown origin, no brand name, don't remember buying it. Pretty obvious what it does, but I don't think it's too necessary, it makes a nice collectible.
I added the timing device also in case someone missed it from a previous post. Also found this fire extinguisher two weeks ago in a large collection of 60's 70's 80's NOS parts
