[Farmall] ih bolts

[jtchall at nc.rr.com]

I think we discussed this a while back but I can’t find it:
Every true IH collector knows they made their own bolts at the West Pullman plant. What came first, IH or WP markings on the heads? What years did IH put these marks on? The bolts with the raised circle (I’m assuming from a parting operation), did these precede the other 2?

Also, did IH out source some of their bearings? I can see it bing a lot easier (cost effective) to make your own bolts. Bearings are a different story.
