Lathe Question

I picked up an older Atlas/Craftsman lathe last month and am having a great time with it. The literature I've seen calls for "Keystone #122" grease on the gear train, but I can't seem to find it or an equivalent product. What's a good grease/oil to use on the straight cut gears on this lathe as well as the gears in the quick change gear box? Is there a modern equivalent to Keystone #122 grease?
