I backed the 511B and 400B back into my new woodshed tonight. I noticed a difference in the nose weights. The ones on the 411 had 6 holes in them,- casting #A20338 and Old Abe was upside down on the 411-H, sn#60232200, The 511B sn#6097184 had only 4 holes in it's nose weights. casting #C-1183, and Old Abe is wright side up.
Question is---waat are the narrow holes in the weights on the 411 for, and what does the "H" signify in the sn. tag on the 411.
