Hi Fred
I now see the two areas you have pointed out.
The one below the throat is if I remember some plating missing and therefore looks funny and a different color.
The link you pointed out looks to be missing the groove so this will be something I will more closely examine when I see it again first hand.
I have examined it once first hand and it mostly looks ok by my limited knowledge taking into consideration it has been around for 75+ years, it is not mint but above average overall condition, everything fits very-very good and the finishes all match plus a very nice blade.
Thanks for you pointed out areas of concern and I will check them out again.
best regards
michael
