Has anyone ever seen stamps like these and what do they mean?
Yeah I was leaning towards the aliens...lol I have talked to some of the best mechanics i know they all think the builder of that motor stamped it as the same time they have no clue cause they have never seen symbols stamped on a balancer weight like this numbers yes seenthat a million times thanks for the inputWhen I was a welder back in the day, we had stamps like that and were expected to place that stamp wherever we laid down a weld so it could be traced back to the person responsible should a problem surface years or decades later. Perhaps this is something like that. The machinist who worked on that piece stamped it?
It's either that or... aliens?
