So I wonder into my hangar the other day and notice my hangar mate bought a new snazzy bore scope. I decide to give it a try on my 0 time SMOH O360 that I recently purchased. I look in the plug hole and see "made in Poland" stamped on the piston (in ink). Poland? Really??? Is this normal??? The rebuild seems to be very well documented with lots of new parts (including the pistons) and was intended to go into a certified aircraft, so I'm guessing this is not a problem. It just seems strange to me. Anyone know anything about these pistons?
