The grids are probably going positive due to leaky coupling caps from the previous stage. A common occurrence in many HA-410's and 460's. The part number (I have all the part numbers for most of the Lafayette stuff at the part level) remained the same for the entire life-cycle of the chassis. The case also retained the same part number throughout its life. All my original manuals for the 410 and 460 showing the variations (2 versions) retained the same physical dimensions.
