I think overall it looks pretty good. The extra holes by the chin scales which have been filled resulted from the helmet being modified from an earlier, taller pattern. Extra holes under the eagle are the result of one or more different spikes/eagles being fitted to it over the years. There may also be extra holes behind the plate. Liners in these earlier helmets are usually of a thick, coarse leather. It has been over polished IMO, but will take on a nice patina with time...
