Anybody got a list, or know a source?
Thanks

Here's some of the numbers (can't id maker on these): 212 21355416 2191127 4095246 414699 3876802 3820618 3855914 These are part of a truckload of unclaimed cranks from a closed machine shop. I've got everything from an inline 8 to a Caterpillar 2-cylinder :confused: Right now I'm just trying to get a reliable list of numbers so I can put these poor cranks up for adoption

I've confirmed one is forged, but there are several others I haven't checked.
It seems from what I've seen that cast and forged cranks would generally have different numbers, but I'm wondering.
