60's vintage Oregon saw bars
John,
Steve here...
Had my buddy Matt mill out the saw bar in the pic to fit the large saws...Seems to oil fine..Very smooth.... The rail is 4/10 deep, but still seems to oil good..
On the 066 the bar didn't seem to oil very well, the oil hole is at the bottom of the groove and the chain couldn't grab it and drag the oil down the bar.

The machining on these old saw bars is awesome, the rails are smooth with no tooling/chatter marks , compared to an off the shelf Rollomatic ES, which is a little rougher, and the tails are so much smaller
