    Remember, these are used parts/tools and will look and act accordingly. I have no specific knowledge as to the history of these parts or their exact original condition. All parts/tools are sold in "as is" condition. There are no warranties expressed or implied. I try to give as good as description as I can and will not sugarcoat any known problems. Since they are used parts/tools, they may have unknown problems that I have no knowledge of. Again, they are used parts, may not be perfect, and therefore may not act like brand new. Do not buy if you are unsure of something. Fitment is the responsibility of the buyer.
    Was with my husband picking up a couple of boat motors and found some cool old airplane tools.
    Really cool old Gabb Accro-Matic radial engine compression testing kit.
    I’ve copied and pasted what I learned…
    This is a complete Gabb Accro-Matic radial engine compression testing system that dates back to the Second World War.
    Rather than having to test each cylinder individually, which could very well take all day, this system allowed aircraft mechanics to screw each tester into a cylinder’s spark plug hole, then crank over the engine and get a compression reading for all cylinders.
    These compression testers work in the same basic way as older-style tire pressure gauges – the pressure pushes a rod out and by measuring how far out the rod has come, you get your pressure reading.
    Radial engines were used extensively during WW2, in fact the single most prolific engine on either side of the conflict was the Pratt & Whitney R-1830 radial, with 173,618 in service.
