Hi Art. I have been following the post for the HL pieces with & without rods, with great interest. This is something that I have wanted to know for a good while, but didn't know how to find out.
I have noticed a good number of discrepancies as far as a low number without a rod and a higher number with the rod. Is this a mistake or is it caused by replacement of broken pieces? How are you going to account for this in determining the actual cutoff of the numbering? And are you going to make your findings ( from this source & others )available? Thanks for your efforts in helping us all!
