TimG,
I hesitate to formalize an opinion on an item which I have not seen in person. I do agree that the first thing I noticed was that there were no visable broach marks.

The seller took quite a few pictures, but left out the most important picture (the deck and pad together) which could help verify the original pad stamping.

The pad was ,in my opinion decked at some point in its past life.

It is however,a very desirable dated L-78 Block.
